Revert "Remove pending publishers from organization_list"

This reverts commit d6870a2089188c74e9c789e0373ec776f60b519a.
Better fix for not showing pending publishers

The internal moderated edits implementation means that any state that
contatins "pending" won't be flagged as current, and the old active
revision will be used on "organization_list". This changes the state to
be "approval_needed". This needs to be updated on the table as part of
the migration.
