[FIX] Composer: Fix assistant position

The composer assistant position was updated with the introduction of the mobile
mode but there are two issues with it:
- the change of CSS rule did not account for cells with the content set
  on multiple lines
- the structure of the bottom bar composer (in mobile mode) still hides
  the formula assistant

This revision reverts the assistant position and simply hides it in
mobile. A future work will try to reintroduce it with a modified aspect
that suits the mobile interface.
