Ensure PauseUIUpdate always ends up getting set to false

when result was null but getTaskbarUIController() is not null, we don't setPauseUIUpdate to false. This CL ensure we always end up setting pauseUIUpdate to false so that the hotseat suggested apps show up.

Fix: 295892343
Flag: no flag
Test: verify hotseat icons don't disappear
