DO NOT MERGE Ensure ScheduledExecutor is not shutdown before scheduling timeout cleanup. 

The scheduled executor in ConnectionServiceWrapper may be shutdown when calling createConference and createCall. This is infrequently causing a `RejectedExecutionException`. This CL adds a check that mScheduledExecutor is not shutdown before scheduling the cleanup.

Flag: EXEMPT Security High/Critical Severity CVE
Bug: 388588560
Test: manually using the provided apk + atest CallsManagerTest
