Fix the duplicated index issue
Optimize the fetching of a saas a little by not even trying to see if there is multiple saas for the same hostname.

A model side validation should validate this beforehand instead, or simply ignore if there is multiple sass's objects for the same host and use the first one.
Update ruby to 2.1
Ruby style guidelines
Doesn’t redirect when no saas are found in development
Fix the order of the field saas_id on the default scoping and indexes.
