[BH] Several classes/lectures don't work

List of affected Classes:

• Fabrication

List of affected Lectures:

• Fabrication
• Robotics
• Research and Debate

I tried to start a Fabrication class using the whiteboard, and I noticed that my customers were not using the objects around, and I was only able to teach Rocket Science at the whiteboard after launching it.

It's a pretty easy to see the issue when I look at the tuning: the interaction to start the class launches a Rocket Science class situation instead for the instructor. 

There is also an other issue while trying to hold a Fabrication Lecture, that I tested with no other mod installed other than the Better Exception: the interaction that is used to make sims join the class causes an issue (the issue is thrown every time a Sim joins the class):

Exception during call to test method on <class 'sims4.tuning.instances.simPicker_HobbyClass_Whiteboard_LectureFor_Fabrication'> (AttributeError: 'SimInfo' object has no attribute 'is_part')
Traceback (most recent call last):

I don't have this issue with other classes, so I don't know what is different here. Tested on multiple lots.

I found the cause: contrary to other hobbies classes broadcasters, the one from the fabrication class uses the "imPicker_HobbyClass_Whiteboard_LectureFor_Fabrication"  interaction instead of the "sI_HobbyClass_ListenToLecture_Fabrication" interaction. So it's also a quick fix 🤩
