Subject: [PATCH] flatpak-installation: Handle an unconfigured remote when
 listing remotes
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

This prevents a crash in flatpak_installation_list_remotes_by_type() if
the `FlatpakDir` can’t ensure it has a repo configured.

Signed-off-by: Philip Withnall <withnall@endlessm.com>
