MDL-65538 competency: fix behat errors with firefox

There is a random behat error when executing the "Go to the competency
course competencies page." scenario: "Moodle exception: A required parameter
(courseid) was missing More information about this error".
It happens because sometimes the form is sent before the JS and it hasn't
the needed parameters defined. So they have been added as hidden to the
form to avoid the error (which I couldn't reproduce manually).
