hotkeys: Don't pass input to RT when non-RT search is in focus.

This fixes the bug where a user cannot type vim keys in the
general search box / user search / stream search,
since they are captured by recent topics.

The behaviour was flaky for stream search, but can be reproduced
consistently after previous commit fixing the popovers.any_active
output.
