Title: ISPN-1882 - IllegalStateException in state transfer when starting a single clustered node

https://issues.jboss.org/browse/ISPN-1882

Also t_1882_51 for the 5.1.x branch.

In invalidation mode the state transfer lock interceptor is not loaded,
so we don't care about blocking write command. However, we have some
common code that blocks/unblocks write commands, so we must ensure that
the blocking/unblocking is symmetrical in invalidation mode as well.
