Insert correct app transition events for recents anim

The transition delay will be the latency until all the leashes
were created etc. Thus, the actual latency is going to be in
WINDOWS_DRAWN_DELAY.

Also fix an issue where we inadvertently started a transition,
and then the transition logger was hanging.

Bug: 72967764
Test: Swipe up from home button, observe eventlog
