Remove dependency on Queue Order

I will note that Queue Order does do what it says on the tin, and allow you to give certain queue's more "weight" than others, and those annotations remain in the codebase for this module. However, there are other methods to control queue operations (such as Ultimate Cron) and Queue Order can cause conflicts. If Queue Order is the preferred method for a website, it can be installed separately, without the dependency.
