Fix aborting transition when deliver to top bellow transient launch

ActivityStarter reports DELIVER_TO_TOP when reusing a transient hide
task. Although there is no visibility change for the reusing activity,
the task order will change so the transition should not be aborted.

Fix: 280387453
Test: pass existing tests
Test: repro steps of the bug and it won't abort the transition
