addtg allow adding multiple same module but different tutorial group

[yumengtan]

A student would not possibly have multiple tutorial groups for a single module - allows multiple tutorial groups for single module as shown below.

Team's Response

We have considered this situation before but decided it is right to allow adding multiple same module but different tutorial groups as in NUS, there exist modules that require students to be in 2 different tutorial groups, e.g. LAJ1201. Since this scenario is possible, it shouldn't be restricted.
