Creating reference without uuid overrides existing one

[trasher]

When creating a new reference; we rely on uuid to update or cretae.

When uuid is empty (from the form when not called from any app); same row is overrided again and again.

As a solution; we should check if uuid is empty from form data; and then call create instead of createOrUpdate. This will not detect any duplicates from the form directly (wll... I see problem several times during my test; maybe not in real life).
