Reset mock transport service in CcrRetentionLeaseIT (#42600)
Browse files Browse the repository at this point in the history 
testRetentionLeaseIsAddedIfItDisappearsWhileFollowing does not reset the
mock transport service after test. Surviving transport interceptors from
that test can sneaky remove retention leases and make other tests fail.

Closes #39331
Closes #39509
