fix(navigator): ignore search events while disabled + invalidate on FlatCreated

useNavigatorSearch had two gaps its tests cover:
- with no active tab the query is disabled, but a NavigatorSearchEvent still
  updated the data; now such events are ignored until a tab is active
- a newly created room (FlatCreatedEvent) now invalidates the
  ['navigator','search'] query and refetches the current search

Fixes the 2 failing useNavigatorSearch tests; full suite 472/472.
