Having a GameObject with multiple missing scripts are creating an incorrect number of editors for the Inspector.
Instead of creating e.g 3 seperate components with 'Missing (Mono Script)' we are instead showing this the multi edit info box:
"Components that are only on some of the selected objects cannot be multi-edited" which makes no sense.
And is a problem if we want the user to be able to cleanup the GameObject (remove or fix the missing scripts)

Repro:
1) Create GameObject
2) Add 3 scripts: e.g TestScript1, TestScript2, TestScript3
3) Make sure they are added on the GameObject in the scene
4) Delete the 3 scripts
5) Notice how the inspector incorrectly shows the info box instead of tree separate script editors
