Work around a Pebble Time Round display bug

When leaving a modal window (i.e. a notification), the watch face redraw
seems triggered correctly but most of the screen end up blank. To work
around it, I mark all the layers dirty in an app "did focus" event
(which is triggered after the faulty redraw).
