Fix bug 5358705 - Request no full-screen mode of the IME when a

SearchView is expanded in an action bar

This is a case where we always know there will be room on screen for
the user to meaningfully use the UI in the absence of full-screen
extract mode. Save the old state and restore it when we go in and out
of expanded action bar mode.
