Plugin reports "no modules defined" when there are modules defined in skaffold.yaml

### Expected Behavior
When there are multiple `skaffold.yaml` modules defined, these modules aren't listed in the `Build/Deploy` configuration "Skaffold modules" section and cannot be selected to be run for a particular Run/Debug config.

Running with a particular module works correctly via CLI:
```
skaffold run -m
```

### Actual Behavior
When there are multiple `skaffold.yaml` modules defined, these modules are listed in the `Build/Deploy` configuration "Skaffold modules" section and are able to be selected to be run for a particular Run/Debug config.
