Description

There are several issues related to websocket connection opening that are surfaced when the there isn't a server listening in the provided address.

To list the issues:

• Open is made in the background, that could cause unhandledRejection.
• Race condition between error handling and opening, causing the promise to resolve and/or the process to exit (depending on the case).

We should refactor how Connection#open() is invoked by the Client to always check that open was previously called and fix the race condition.
