Can't sign in using OpenID

[Anthony Lenton]

Signing in using OpenID fails with an ugly error message:

Traceback:

Exception Type: InvalidOpenIDNamespace at /openid/complete/
Exception Value: Invalid OpenID Namespace u'http%3A%2F%2Fspecs.openid.net%2Fauth%2F2.0'

It seems that the OpenID namespace is being escaped when it shouldn't be at this point.

Notes to QA:

This is fairly straight forward to test, as you can't sign in to the site if this is broken. If you can submit an app, or view an app's details, this is working.
