### What?

This PR ensures defaultSort is reflected in join tables.

### Why?

Currently, default sort is not reflected in the join table state. The
data _is_ sorted correctly, but the table state sort is undefined. This
is mainly an issue for join fields with `orderable: true` because you
can't re-order the table until `order` is the selected sort column.

### How?

Added `defaultSort` prop to the `<ListQueryProvider />` in the
`<RelationshipTable />` and ensured the default state gets set in
`<ListQueryProvider />` when `modifySearchParams` is false.
