SM resumption of a session that had an SM error causes NPE

Description

With Stream Management enabled, some (SM) related errors can cause the feature to be silently disabled. One example of such an error is an overflow of the queue of to-be-acked stanzas.

When a client attempts to resume such a session, the following NullPointer is thrown. Instead, the resumption request should have been answered with a failure response.
