Describe the bug
When the lesson timetable for a module is changed by the faculty, the lesson indices in the config points to the wrong lessons.
To Reproduce
WIP
Expected behavior
A better implementation of the validation logic should be able to compare the cached timetable before the module update and the timetable after the change, in order to recover the config that the user has created before the faculty changed the timetable.
Additional context
This is caused by #4225
