The option 'add to spreadsheet' works under the hypothesis that the
current action is a ViewManager. It crashes in other contexts (e.g. in
Messaging, mail box), as it tries to retrieve the list_view id of the
ViewManager.
We now only add the option in the Favorite menu if the current action is
a ViewManager.
The search view has been split into two widgets: SearchView
and SearchViewDrawer. The addons board and google_spreadsheet need
to be updated to append their input widget to SearchViewDrawer and
not to SearchView.
