fix test helpers for relative_url_root

[evanboho]

BUG:

• in Rails 4.2, Devise goes into an infinite loop if relative_url_root is not set in the Rails config
• when relative_url_root is set, Devise's test_helpers do not pass the attempted_url in the warden options
• this causes an error at Pathname.new(attempted_path) in the failure_app

FIX:

• add attempted_path to the warden options in the test_helpers

Versions:

• Devise 3.5.6
• Rails 4.1.13
• Warden 1.2.6

@evanboho thanks a lot for the fix - any chance we can write a test case for this?

@evanboho Thank you for your report. Could please give more information in how to reproduce this bug?

In your description, you have mentioned about an infinite loop on Rails 4.2. But in the end of description you've mentioned the versions you tested was Devise 3.5.6 and Rails 4.1.13.

I've downloaded your branch, but your branch is running Devise 3.0.0.rc and Rails 4.0.0.rc1. I've uncommented the code you added and test suite is passing.

Could you please give us more information in how to reproduce it?
