Right now, when adding a testimonial via the admin, you can select a contact, but then you have to manually type in the Author Name and Author Email, despite being connected to a contact. It's like... displayed right there, but we can't even copy and paste, we have to type it out, since author name at least is a mandatory field.
Sure, we might want to change those values, but by default it should be the same as the contact we've selected.
