Fix relayout requests when dragging

Also removed unneeded legacy code that shows the keyboard when
the search view is focused. The framework does that automatically for
us, and this code was causing problems by popping up the keyboard
whenever you dragged a contact over the search view.

Also turned off debug flag.
