Get specs running under rails 4.2.0.beta-1

[johnnaegle]

The 4.2.0.beta-1 specs are failing because the released version rails-deprecated_sanitizer gem includes Rails::Railtie. This is fixed (rails/rails-deprecated_sanitizer#1) but not planned for release.

This change uses the github version of rails-deprecated_sanitizer for 4.2.0.beta1

There is one failing test under 4.2.0.beta-1 when this is merged in.

Turns out they pulled rails-deprecated_sanitizer as the default configuration for 4.2.

Thanks for looking into this though.
