Sidebar channels list rendering multiple times #328
Description
https://github.com/buddycloud/webclient/blob/dev-candy/js/app/views/sidebar/Channels.js#L165
Channels view tries to fetch metadata from every followed channel, it's possible the data to not be already at the database (error event is triggered), and it's possible that the server triggers an error as well.
There are three possible situations:
- All requests succeeds eventually (already from db, or after a db error)
- Some requests fail (error at db and error at server) and some requests succeed (success at db, or error at db and success at server)
- All requests fail (db AND server)
Right now, the view tries to render after every metadata request.
