Prevent triggering ng-focus on input during completion

$apply during another $apply is not possible, and .focus() on the input node
triggers the ng-focus on it (which hides the sidebar, if on mobile), so to
prevent the exception from being thrown, move the input node focusing
out of the $apply with a timeout of 0.
