_This doesn't seem to affect functionality_
There are 2 distinct errors in the console when starting/stopping process
groups either from the operation control or the context menu:

Both appear related to the reducer assuming the response of the api call
returns the whole object with `permissions` and such. in the case of process
groups, it is a very sparse return object and doesn't have those.
We should be sure the "fix" works for all startable/stoppable components.
