UnsafeLoader does not use UnsafeConstructor

[dthkao]

Is this intentional?

#472 moves some of the multiconstructors form FullConstructor to UnsafeConstructor and updates tests to use UnsafeLoader (this makes sense), but UnsafeLoader does not inherit UnsafeConstructor (no loader does).

There doesn't seem to be a way to use UnsafeLoader if needed?

Oof disregard. I now see that Constructor=UnsafeConstructor, and that our broken tests aren't specifying a loader (ew).
