Fix Railtie to pass class when setting options

This will clean up the railtie quite a bit, rather than passing a set of
hash keys call the new class directly like we do with ActiveJob.

Only call driver once when tests start rather than in every single test
setup. This is more performant, and the other way was creating
unnecessary calls.
