Clear invisible transition info

Browse Source 
If 2 independent launch events happen in a short time, e.g. the
first activity is only added to the stack with initial states,
and only the latter is actually launched. Then the invisible
transition info (the activity occluded by the latter) should be
dropped. Otherwise when returning to it from back stack, the
transition time will still be counted from the time it added.

Test: ActivityMetricsLaunchObserverTests#testOnReportFullyDrawn
