Prevent sending early termination of appop use

If a package starts a particular appop both as active and noted, once
one of them is finished (usually noted after 5s), a message will be sent
to callbacks indicating the end of the use. However, the app op may
still be active. This could result in the removal of indicators
prematurely from notifications.

This change prevents that from happening by checking if the app op is
still in use by that combination uid/package (either active or noted)
and not notifying listeners if that's the case.

Test: atest AppOpsControllerTest
Test: use app from bug report. Observe that notification does not lose
the microphone indicator
