Title: Fix logging FileConfiguration validation function.

Check that file logging is actually enabled before checking if the
archive logging configuration is valid. Also add a unit test to check
that the defaults are valid.

This is the same as the fix mentioned on the [user group](https://groups.google.com/d/topic/dropwizard-user/2aE1un1dpN0/discussion).
