GsFlatpak instance can be NULL if there are other apps for
download coming via other plugins. Since the last reference of
GsFlatpak was in the previous loop and the check is outside
the loop, this seems as a logical error. Instead, check if the
current plugin as no apps to download and if so, return early.
