Revert inline? patch. Fixes #83

After looking at the code in Resque itself for inline, it should just
work without any changes in Resque::Status. If you're using inline
with the idea that you'll be able to mock out redis, though, this
will not work as even with `inline` Resque::Status will still depend
on Redis to work. You can get around this with using a mock redis
library like: https://github.com/causes/mock_redis
