RIA4: Having an issue with my sign_in_as! helper method I've defined in my integration tests

I’m having a frustrating issue where my sign_in_as! helper will not fill
out the password in my seeds_spec test. However all other integration
using the helper still pass which is very confusing for me.

I put a call to sleep in for the method, and ran the test with webdrive
fill in the password manually, and the test completed as it should.

Any ideas? Code: https://gist.github.com/Senjai/6382416
