Fix T60402: Increased data.users value, when running: C.active_object.to_mesh(C.depsgraph, True) - on curve.

More like a band-aid than anything else really, that code is horribly
weak and need to be fully re-written at some point (putting all those
temp data-blocks fully outside of bmain...). But for now should do.
