Stepping through both versions, it looks like the crucial thing is that
org-agenda-get-represented-tags needs to be called _before_ the
completion function.  If it's not, org-agenda-filter-completion-function
calls -get-represented-tags with an unset cache, and it returns nil
because the (derived-mode-p 'org-agenda-mode) condition is nil.

The same goes for org-agenda-get-represented-categories.
