Steps to reproduce:

1. Create a face-to-face session with multiple dates
2. View the session on the upcoming sessions pages

What should happen:

Dates displayed in correct time order.

What actually happens:

Fix:

Change the following line of the face_to_face_get_session_dates() function in facetoface/lib.php:

if ($dates = get_records('facetoface_sessions_dates', 'sessionid', $sessionid)) {

to:

if ($dates = get_records('facetoface_sessions_dates', 'sessionid', $sessionid, 'timestart')) {
