CleanUp#clean: Replace `#destroy_*` calls with `#run_methods`

It turns out that we don't care about destroying orphaned data. From

Replace the calls to
`#destory_{vehicle_journeys,journey_patterns,routes}` with one to
`#run_methods`. This change allows callers to run any cleanup methods
defined in `CleanUp`. For example:

    CleanUp.new(methods: [:destory_routes])

But now by default, none of these destroy methods are run, saving us
from doing extra work that it turns out we don't need to bother doing.
