Temp fix for a crash faced by client using proxy connection#1493
Conversation
Explanation: `ARTSRProxyConnect` object can potentially generate a proxy connection error even after initial success (or more than one error in a raw), which can depend on what proxy type is used, which will create a race condition: `self->_proxyConnect = nil;` deallocates `ARTSRProxyConnect` object on a `_workQueue`, and a subsequent call to `_failWithError:` on a `io.ably.socketrocket.NetworkThread` inside `ARTSRProxyConnect` will cause crash when it'll try to access `self`.
