Migrate table exists but not found on Shell

**Actual Behaviour**

I'm using serverless with python and using docker with dynamo:
https://github.com/dwmkerr/docker-dynamodb

now created the docker container with port 8000 shared with localhost.
ie:
```
dynamo:
image: dwmkerr/dynamodb
ports:
- "8000:8000"
```

then after I activate the container, I run the migrate command:
`sls dynamodb migrate --account local --port 8000 --host 127.0.0.1`

Im aiming to my localhost on port 8000 as the port is shared with the docker container.

now when I run the command for the first time, it says the table was created. That's great.
When I run for the second time, it says: table already exists. That's great.

But when I access the shell on
`http://localhost:8000/shell/`
and try to list the tables, I dont see it...

Any ideas what is missing here?

**Expected Behaviour**

created table, do not appear on shell.

**Steps to reproduce it**

- create a docker-compose file with the image above
- create the container and let it run
- run the dynamo migrate command while pointing to that dynamo instance
- check tables on shell

**LogCat for the issue**

no crash.

Start by reproducing the Docker setup, the `sls dynamodb migrate --account local --port 8000 --host 127.0.0.1` command, and the shell at `http://localhost:8000/shell/`. Compare the migrated table's visibility through the migration command and the shell, then confirm that the created table appears in the shell listing without changing the reproduction steps.
