In sctransport.js, consider emitting disconnect/connectAbort event after calling _abortAllPendingEventsDueToBadConnection

[Jonathan Gros-Dubois]

Ideally disconnection should happen after events have been cancelled.
Right now this is not the case: https://github.com/SocketCluster/socketcluster-client/blob/master/lib/sctransport.js#L211

First, check that switching the order doesn't cause any negative side effects.

This ordering of events on the transport object is necessary to allow the socket to handle the disconnect cleanup operations at a higher level before they are cleaned up at the lower (transport) lever.
