This reverts commit 3c611393.

The filter annotation for ordering by show ownership introduced
a join that caused some results to appear more than once.

The dashboard will need to implement a paginated list of shows
that should be searchable.

The dashboard must be able to sort shows.

In aa7e7f41 filters were renamed
to a camelCase scheme. This is actually wrong, because the filter
names are already transformed to snake_case when the are applied
to the FilterSet.
