MDL-78578 enrol_lti: permit launch cache access during launch redirects

Browse Source 
This handles things like site policies, which store the current URL,
redirect to the policy agreement, then redirect back the current URL
afterwards. In such cases, we want to redirect back with 'launchid' set
so that we can fetch the id_token from the session cache. This is the
same thing we already do during account binding, so the patch only
makes sure the PAGE->url is properly set before calling require_login.
