When the flatpak application has access to the host cache media art,
it is able to load the media art from host cache and display it in all
the views and widgets. However, the URI passed to the MPRIS client is
the container's one. Therefore, the MPRIS client try to load an uri
which does not exist.

Fix the issue by removing the host xdg-cache/media-art access. This
means that the flatpak application does not use the system cache and
creates its own.

Closes: #253
