 discussion in #meta] with @otto42 and @ipstenu.

 Under some circumstances, it's possible to have plugins with duplicate
 slugs:
 1. Open a plugin with a `new` (Pending Initial Review) status for editing.
 2. Change the slug to another existing plugin's slug.
 3. Click "Mark as Pending".
 4. There are now two plugins with the same slug. Whichever one is updated
 next will get a `-2` appended to its slug, causing some confusion.

 Changing the slug to another existing plugin's slug should be disallowed.
