Remote transactions can be registered after cache stop and block shutdown

The cache status check is done in InvocationContextInterceptor, but by that time the remote transaction was already registered, and there is nothing to remove it from the transaction table.

This can be seen in TerminatedCacheWhileInTxTest, which logs ""Wait very briefly and then make call." and then proceeds to wait for 30s (i.e. until the cache shutdown timeout expires).
