No error/warning/info if password is incorrect

I was initializing your driver as described in the examples but my redis server was down.

rsmq-promise doesn't give the developer any information if the connection was successfully established while rsmq allows to listen via events (it's an EventEmitter).

Furthermore, when methods like listQueues are invoked, they seem to simply not return or have a big timeout threshold. This makes it difficult to work with this library unfortunately.
I'd like to get feedback on whether my connection was established (at least at the time when I'm executing a function on it).
