When you pass a function to completing-read, it is not used to generate
the list of canidate completions. As documented:
collection can be a list of strings, an alist, an obarray or a hash table.
collection can also be a function to do the completion itself.
predicate limits completion to a subset of collection.
See `try-completion' and `all-completions' for more details
...
collection can also be a function to do the completion itself.
It receives three arguments: the values string, predicate and nil.
I think what you want is:
(defun matt/external-addressbook-completion (stub)
(interactive (list (completing-read "Name: "
(edsquery-return-addresslist "")
nil t))))
