Dispatch methods should not include listeners for other state models

[CaptainCodeman]

The reducer or effect that listens for action from another state model should not appear in the list of methods for a model.

Should be callable:

effects: (dispatch, getState) => ({
  load: async () => {
    //
  }
})

Should not be callable:

effects: (dispatch, getState) => ({
  'auth/signedIn': async () => {
    //
  }
})

Anything containing '/' needs to be filtered out of the types (not sure if Typescript supports that, it would mean a condition based on a string match on a key)
