Fix URL to terms of use.
Update terms of use test which had a scheme missing from the terms of use url.

This test should not pass on Travis until after Sander van der Waal's pull request (#646 on github) has been accepted.

This fixes #647 in github's issue tracker.
Merge branch svanderwaal's master branch into 647-broken-terms-of-use-test
Merge pull request #1 from openspending/647-broken-terms-of-use-test

Broken terms of use test
Merge remote-tracking branch 'sander/master'

Conflicts:
	openspending/ui/templates/account/login.html
	openspending/ui/test/functional/test_account.py

Needed to migrate the login page changes to the jinja template and update the tests (they now provide headers since WordPress farm requires it).
