Fix cfbot failure caused by commit 228c370868.HEADmaster

Ensure the test waits for the apply worker to exit after disabling the
subscription. This is necessary to safely enable the retain_dead_tuples
option. Also added a similar wait in another part of the test to prevent
unintended apply worker activity that could lead to test failures
post-subscription disable.
