Rahul Frias cb8bb251e4 Remove ExpiryOnReleaseOfflineKeyTest
The test verifies that a downloaded license receives an expiry event
in a session if it is released from another session. With
the introduction of the big usage table feature loading a
license/usage entry into multiple sessions is not permitted and
so this test is no longer needed.

Some OEMCrypto implementations might require OEMCrypto_UpdateUsageEntry
to be called between calls to OEMCrypto_LoadKeys and
OEMCrypto_ReportUsage. This CL adds the call to
OEMCrypto_UpdateUsageEntry.

Test: WV unit/integration test
Test: Playback using play movies and netflix
Test: GTS tests
