Title: Correctly handle nil assignments

Small change that addresses \#51

When assigning nil to a translated attribute, active_record changes are correctly tracked and therefore validations (if any) have a chance to fire correctly.

Tests added to cover the dirty changes tracking.

This may have implications for fallback configuration, however this change didn't break any existing tests so I'm assuming all is well ;-)
