When a user opens a record in a form view, the chatter is
displayed. Then, if he clicks on 'Create', the chatter is removed
from the DOM (there is no chatter in create mode). After saving
the newly created record, the chatter is displayed again, but the
same widget's instance is kept.
However, when being removed from the DOM, the event handlers bound
on elements of the chatter (e.g. 'New Message', 'Log a Note'...
buttons) are automatically unbound.
So before this rev., the buttons didn't work anymore once the form
view had switched to create mode. In this commit, we detach the
chatter's $el before updating the view, so that its handlers aren't
unbound when the old content is replaced by the new one.
