Fix black screen after moving top activity to another display
The screen was black after moving the top activity to another display.
The next top activity did not be resumed and was still invisible. The
regression was from bebd8cd, which incidentally reverse the condition.
Since the case of removing a display is already handled by 402b440,
#postReparent is not needed to call again in #reparent (when display
is removing).
Fixing the issue forward by resuming the focusable task in
#moveRootTaskToTaskDisplayArea.
