Previous to this commit, the gjs tests were installed-only; and our
logic for handling the "--enable-installed-tests=exclusive" logic
actually also meant they weren't installed.
It did work for me locally with `--enable-installed-tests`.
However, to make things fully symmetric, let's enable the js tests to also be
run under `make check`.
Also remove `corrupt-repo-ref.js` from the PAPR invocation since it's not
actually a unit test, it's a utility helper.

Allow GI bindings to delete refs through ostree_repo_transaction_set_ref
and ostree_repo_transaction_set_refspec by setting the checksum to NULL.
