Test this project with Rails 4.2.5.rc1

[rails-bot]

Hi team,

we just released Rails 4.2.5.rc1. To help us to find regressions, and make the final release
awesome for everyone, I'm here humbly asking you to test your project with this
Release Candidate.

We are planing the final release to 2015-11-04, so it would be great if
you test it before this date.

If you find any regression please open an issue on GitHub mentioning me and with the title starting
with:

[Regression 4.2.5.rc1]

Thanks in advance.
