Reduce redundant IPC when switching app by navigation bar 

In SplitScreenController#onStartingSplitLegacy, it also ignores:
if (ENABLE_SHELL_TRANSITIONS) return null;

This avoids a latency from the 2-way IPC in
RecentsAnimationListener#onTasksAppeared.

Bug: 275508603
Test: Capture trace when switching app by quickstep.
