## Current Behavior
<!-- This is the behavior we have today -->
When running `nx list`, if a plugin has no capabilities (i.e.
`@nx/eslint-plugin`), it will show brackets with an empty list of
capabilities.

```shell
$ nx list

## Expected Behavior
<!-- This is the behavior we should expect with the changes in this PR
-->
When running `nx list`, if a plugin has no capabilities (i.e.
`@nx/eslint-plugin`), it won't show brackets with an empty list of
capabilities.

```shell
$ nx list
nx list
