[FIX] update the searchview tests

to accomodate the fact that the searchview has been changed.
Two changes need to be accounted:
(1) the drawer html structure has changed (oe_selected class is
replaced by badge, some li tags are replaced by spans, ...) and
(2) the CustomFilters has been split into CustomReports and
SaveFilter, so there is an extra filter in the drawer inputs.

Also, the searchview need a parent to react to the switch_mode event,
so the tests add a fake parent to the view in make_search_view
