Connection Error handling problems

A managed connection that encounters a fatal error and calls ConnectionErrorOccured on the GeronimoConnectionEventListener may not have the resources held by geronimo cleaned up properly.

In particular, if several ejbs have handles to this mc, the connection tracking won't work properly. Only the currently active component (ejb) will have it's handle(s) removed from tracking. When the other handles are disociated or closed, errors are likely, such as putting the destroyed managed connection back into the pool.
