Check() when loading a child anim BP used as a linked instance

Check encountered by CloudChamber. Slack thread:
[Link Removed]

From Slack:
if I use that ChildBP as a LinkedInstance in another AnimBP and then close the editor and reopen it, I hit the following check when trying to open the AnimBP

check(NewAnimBlueprintClass->GetSparseClassDataStruct()>IsChildOf(RootAnimClass>GetSparseClassDataStruct()));
