Problem:
Currently, when a Schema has an identifying information but is still empty the element appears as a small gray square:
Once we'll add the edit link inside the element, the Schema will not be empty anymore but it'll still look something like this:
We want to make this nicer by not showing the gray box when no Schema text is there and replacing the edit link with a "add Schema" link.
BDD
GIVEN a Schema page
AND the Schema text is empty
THEN no gray Schema text box is shown
AND a "add Schema" link is shown instead of the usual edit link
Acceptance criteria:
- when Schema text is empty then no gray boy is shown
- when Schema text is empty "add Schema" link is shown
