Get component name from components list not from the component's model

Only 2 nitpicky questions, up to @jessebaker to decide how to handle those 😊

Even though this was RTBC before ✨ AutoSave Entity Revision POC Active , un-RTBC'ing this because that other issue is an order of magnitude more complex, and moves some code around that this MR would have made obsolete. This MR should now remove the code that that moved.

Will do the reroll here! 🤓
