Avoid crash with Connector failure race condition
We were seeing crashes on macOS on a slept laptop overnight, very rarely.
The backtraces pointed to accessing a deleted currentConnection in
Connector. Eyeballing the code for a path that could trigger this,
if the timer fires onTick, queing on the eventloop, and before that event
is processed the connection queues onConnectFinished in the event loop,
currentConnection will be reset by the timeout tick handling, and will
then boom when the handleConnectionConnectFinished is called for
onConnectFinished.
