  REGRESSION(314352@main): [EME] Deferring MediaKeySession teardown leaks the 
CDM session into the next test
https://bugs.webkit.org/show_bug.cgi?id=316101

Reviewed by Xabier Rodriguez-Calvar.

This makes MediaKeySession teardown synchronous again, instead avoiding
the promise resolution when we are tearing down.

Tests clearkey-mp4-playback-destroy-persistent-license.https.html and
clearkey-mp4-playback-retrieve-persistent-license.https.html cover the
CDM session leaking scenario, while
mock-MediaKeySession-backforwardcache-prune-crash.html verifies that
the promise is not incorrectly resolved.
