Add error handling for start task and intent

Browse Source 
If user start task and intent with same app but not support
multi-instance, in this case it will only start one side split and
the other one show as black screen.
We should avoid such status and do some error handling, this patch
prevent it by exiting split immediately and expand the that app as
full screen.

Fix: 224888879
Test: manual
Test: pass existing tests
