npm test failed "Cannot find module 'noop-trigger-feed'"

Hello,

I've deployed openwhisk to Kubernetes by following [openwhisk-deploy-kube](https://github.com/apache/openwhisk-deploy-kube) using kind and the helm charts. I'm using an external couchdb as described in [Using an external database](https://github.com/apache/openwhisk-deploy-kube/blob/master/docs/configurationChoices.md#using-an-external-database). I tried to set up the openwhisk pluggable provider and run the tests using ```npm test``` but the tests fail. The parameters I set and the steps I followed are described below:
My node version: v15.13.0
```
cd provider
npm install .
export DB_URL=172.18.0.1:5984 #url of the external couchdb instance
export TRIGGERS_DB=trigger_
export ROUTER_HOST=172.18.0.3:31001 #url of openwhisk nginx container
export DB_PROTOCOL=http #protocol of external database
export DB_HOST=172.18.0.1:5984 #url of the external couchdb instance
export DB_USERNAME= #username of the external couchdb instance
export DB_PASSWORD= #password of the external couchdb instance
export EVENT_PROVIDER='/path/to/locally/installed/noop-trigger-feed'
npm start
```
The output for the above steps is:
```
> openwhisk-pluggable-provider@0.0.1 start
> node app.js

[2021-04-05T20:59:22.011Z] [INFO] [??] [pluggableProviderTrigger] [createDatabase] creating the trigger database http://admin:admin@172.18.0.1:5984

[2021-04-05T20:59:22.056Z] [INFO] [??] [pluggableProviderTrigger] [initAllTriggers] resetting system from last state
```
On a separate terminal I ran the following commands:
```
npm install ../../provider/tests/resources/noop-trigger-feed/ # from the openwhisk-pluggable-provider/actions/event-actions folder
```
Then, from the event-actions folder I ran the following script :
```
var test = require('noop-trigger-feed')
console.log(test)
```
I get this output:
```
[Function (anonymous)] { validate: [AsyncFunction (anonymous)] }
```
This was to ensure the actions have access to the trigger-feed module. I then ran these commands:
```
export OPENWHISK_HOME=/home/linuxbrew/.linuxbrew
export OW_NOOP_FEED=/guest/noop-trigger-feed/changes
export OW_APIHOST=172.18.0.3:31001 #url of openwhisk nginx container
export OW_API_KEY= #auth key set using wsk property
export EVENT_PROVIDER='noop-trigger-feed'
./installCatalog.sh triggers_ guest
```
Two actions are created:
```
actions
/guest/noop-trigger-feed-web/changesWebAction private nodejs:10
/guest/noop-trigger-feed/changes private nodejs:10
```
Then from the provider folder I ran ```npm test``` and got the following response:
```
> openwhisk-pluggable-provider@0.0.1 test
> ava tests/index.js

should be able to create trigger with pluggable provider feed source

tests/index.js:58

57: // register trigger feed with provider
58: const create_result = await ow.feeds.create({name, trigger: TEST_TRIGGER, params})
59: t.true(create_result.response.success, 'create trigger feed worked')

Rejected promise returned by test. Reason:

I had made the following changes to the files in the repo:
1. Commented out [line](https://github.com/apache/openwhisk-pluggable-provider/blob/3e89db4fc6a2f4e17c98de3885ab0d09fe02a31f/installCatalog.sh#L112)
2. Commented out [lines](https://github.com/apache/openwhisk-pluggable-provider/blob/3e89db4fc6a2f4e17c98de3885ab0d09fe02a31f/provider/tests/index.js#L20-L21) and replaced with:
```
var test = require('ava')
var openwhisk = require('openwhisk')
```
due to error. “Cannot use import statement outside a module”
3. Added 'ignore_certs: true' to [line](https://github.com/apache/openwhisk-pluggable-provider/blob/3e89db4fc6a2f4e17c98de3885ab0d09fe02a31f/provider/tests/index.js#L39)
