Refactor rtc custom events map

[thyal]

Description

Current implementation works but is error-prone since we just write out action type strings. This means whenever an action creator changes name this list would need to be manually updated, and it's too easy to miss that.

This PR use the action creators directly, and rely on the isAnyOf helper to match on actions.
Depends on #186 because I did some changes to the action creators there.
