Ad overlay view leaks via IMA AdsManager after destruction without ALL_ADS_COMPLETED

[andrewlewis]

Issue description

In the IMA extension, if the AdsManager is destroyed before the ALL_ADS_COMPLETED event is raised by IMA, the ad overlay view is leaked, which in turn can leak its activity.

Note: This is a bug in dependency, but I'm filing this issue as a tracking bug for people who want to be updated on the status of the issue. [Internal: b/155041144]

Reproduction steps

Run the demo app. Attach Android Studio profiler. Run an ad playback with the IMA extension. Return to the sample chooser. Take a heap dump and observe that the PlayerActivity has leaked.
