Ensure that a PIP activity gets stopped before MW/PIP mode changes.
- Adds a workaround to ensure that onStop() is dispatched to the PIP
activities when the PIP is dismissed
- Consolidating dismiss PIP behavior to call moveTaskToFullscreen().
Now we are consistent, and when we expand the PIP, we call
moveTaskToFullscreen(top), and when dismissing the PIP we call
moveTaskToFullscreen(bottom)
- Fixing issue where we were dispatching extra MW/PIP mode changes when
just expanding the PIP
- Fixing typo in last commit where PIP mode change was not getting
scheduled correctly
- Fixing issue where move-to-fullscreen log was sent for each task
