Improve search keyboard dismissal (#317)

I need to test this more

Fixes the imeAction for search

Initiating the search will move focus down if results are available

Pressing back while focused on the search text box will move focus to
either the results or the nav drawer. I think will will help devices
that do not dismiss on the soft keyboard on back.

Might fix #311
