Show correct issues for team dashboard (#14952)

* fix no items under /org/$org/{issues,pulls}?type=mentioned

it was filtering by org id, but org-mentions are not persisted like that
to the DB, we need to filter by UID.
This means, selecting different teams will only have an effect on the
selected repos, otherwise results will be the same, which may be
suboptimal.
