Fix the tests checking the User-URL printed in the logs
    
    In 7b917130b9c59a0c9dcfe2990037780977e13f8e we fixed the User-URL logged
    so it is a valid URL.
    Apparently we/I forgot that this was in fact covered in the tests which
    were thus failing.
    This commit fixes that situation and thus the test suite.
