[FIX] mail: improve activity view and fix activity feedback

-Improve no content helper on activity view

-Update chatter after editing an activity un form view

-Avoid context to appear as feedback
When using call_button the context is set as an arg and will be catched by
the kwargs of the called action.

As for action_feedback, we can create a wrapper without kwargs
used when calling this method from a button to avoid this problem.

Another solution would be to change the call_button in order to give
the context as a kwargs. Maybe a possible improvement for master.

-Remove groupby from activity view
group by has no effect on activity

-Change cursor to pointer on record name in activity view
