Stop url_for double-encoding .'s in password test

One of the changes this pulls in is encoding of
periods in the token used for new password
requests.

In real-life the resulting URL is build by
concatenating the base url with the token so it
isn't processed further.

The test for new password requests builds the URL
with url_for. This encodes the result returned so
the periods are encoded twice.
