Inconsistency in Action info API

Consider the following API, and one example using the default whisk.system namespace:
`GET /namespaces/{namespace}/actions`
`GET /namespaces/whisk.system/actions`

The API returns an array like this:

```
[
{
name: 'wordCount',
...
namespace: 'whisk.system/samples'
}, ...
]
```

Then we have the following API
`GET /namespaces/{namespace}/actions/{actionName}`

If we take the `namespace` value of the action and `name` value of the action we would create the following REST call:
`GET /namespaces/whisk.system/samples/actions/wordCount`

But this URL is invalid. The URL that does work is:
`GET /namespaces/whisk.system/actions/samples/wordCount`

I understand `samples` is not the `namespace` and neither the `actionName`, it's the `package`.
So I would expect the following action structure in the first place:

```
[
{
name: 'wordCount',
...
namespace: 'whisk.system',
package: 'samples'
}, ...
]
```
