Stop calling hook twice

[eileenmcnaughton]

Overview

Stop calling hook twice

Before

Relationship pre hook called twice on import & when creating current employer (and a JMA extension)

After

Only called once - per standard behaviour

Technical Details

Per the code comments this hook is called here but also in add. This is all about the crazy
history of this function - which used to be tied to the relationship form.

I can't think of any valid use for calling the hook twice - but I can think of reasons it
would be bad...

Comments
