Fix close during reconnect wait period

If the connect close method is called while the connection is waiting
for a reconnection attempt then the attempt is cancelled but the close
method then erroneously waited for a close event that would never
happen.  Fix by resetting the connector and rasing the close event in
the close method if it's in the waiting for reconnect state.
