NIFI-1984: Ensure that locks are always cleaned up by NaiveRevisionManager
Ensure that if an Exception is thrown by the 'Deletion Task' when calling
NaiveRevisionManager.deleteRevision() that the locking is appropriately cleaned
up.
Looking through the code, there do not appear to be any other places where
we invoke callbacks without handling appropriate with a try/finally or
try/catch block.
