Fix Workers Connecting to Broker Twice

[ABrain7710]

Many of the workers have shown in the logs that they connected to the broker twice. While it hasn't seemed to cause any issues, it does not need to be happening. I figured out that the method call for a worker to connect to the broker was being made in the __init__ method of the Worker class and the WorkerGitInterfaceable class. And since the WorkerGitInterfaceable class inherits from the Worker class, any time the WorkerGitInterfaceable class is instantiated, the broker is connected to twice. With a worker this happens because most of them inherit from WorkerGitInterfaceable. As additional proof that this is the issue, you can see that workers (facade worker) that inherit from just the Worker class don't have the issue, but workers (github_worker, pr_worker, gitlab_issues_worker) that inherit from WorkerGitInterfaceable do.

Looks good. I would merge if it runs like normal like this which I'm pretty sure it would
