Handle some tricky Comm lifecycle issues...

Handle some tricky Comm lifecycle issues * If the comm was a primary comm, but there was an error opening it, _closed was False, which is wrong * If Comm.close() was called, but an error happened, it still appeared to be open This change makes the _closed attribute more conservative. If _closed is False, the comm is definitely open for messages. If _closed is True, we either didn't initialize correctly, or we tried to close at some point.
