Add observables within channel
This relates to !1179 (merged) and follows on from our conversation on Monday @msantang78
Two small additions should be made to the above MR
- Make channel bio an observable, so when a bio is updated via channel settings, it's reflected immediately within with the about tab. Currently used has to navigate away, and then back to the about tab for the newly updated bio to be reflected.
- Make feed list an observable within a channel feed. After a new post is created from within a user's channel, it should appear immediately within the feed. i.e. the user should not need to pull to refresh to see their new post
I'll keep the above MR labeled as a WIP until the above two actions are completed.
