Heroku unable to load rails helper

[goodwill]

I got into something like named route missing for searchlogic_path, which turns out the rails_helper is not able to load properly for some reason in the thin environment. I have forked the project and changed the way how the rails_helper hook on it, also now that use alias_method_chain instead of trying with super as it seems like FormHelper overriding doesn't look exactly like an inheritance approach.

The fork is here:

I have actually sent a pull request before.
