desktop-shell: Correctly migrate views to other outputs when output is disabled/disconnected

Our case is when the view is the same as output being disabled/disconnected.
There's not need to check the views' output with the output being disabled
because weston_view_assign_output() already changes the output of the view when
the output has been disabled/disconnected hence the check is not needed at all.

The views' output will always be different than the output being disabled.

By the time shell_output_destroy_move_layer() gets called the views' output has
already changed to a "free" output. Tested this by unplugging/disabling the
output on purpose.
