keyboard: Do not 'swallow' first taps in group screen

We open Create Group screen with a keyboard open. That is OK.
But then tapping on a user as a first action hides the keyboard
but does not add the user.

Instead, tapping the user now adds it, and tapping outside the
user list will hide the keyboard.
