Clear the search when the launcher is left, end keyboard search on dismiss

Two fixes on top of the type-to-search feature:

- The search no longer survives leaving the launcher. Upstream only resets the
  search when the launcher was in the background for more than five seconds, so
  a quick app switch or a fast return from a launched app left the old query on
  screen. The search page is now always reset, whatever the pause was.
- Dismissing the search page ends the keyboard driven search. Without that the
  flag stayed set, so opening the search later (gesture or search bar) did not
  focus the text field and the soft keyboard stayed away.
