Student's lab grades shown when they don't have lab group.

[wyongqiing]

In the user guide, tutorial group and lab group is specified to be optional, only one is enough.

But, there is a bug where it can have lab grades when they don't even have lab group. Just like when tutorial group is not added to that student, it will not have attendance. It just not make any sense.

Suggestion: make both tutorial group and lab group compulsory to be added.
