Edit contact, on error state button stays gray

[gkarmas]

When I am editing an existing contact, if a field is empty, the Save button stays gray for ever.
I need to close the modal, lost all edits, and redo it.
Same thing applies for a new contact, if something is missing, you need to refresh and start all over again.

I found a possible solution.
Replace on _contactsEdit.js
Line 15: alert(error);
to console.log(error);
Somehow it works.
