    flatpak: Always drop internal caches for both installation instances
    
    When a refresh is requested, always drop internal flatpak caches
    for both FlatpakInstallation instances, to ensure they both agree
    on the local cache content. Otherwise the other FlatpakInstallation
    uses stale data and can error out on calls when being used.
    
    An example: the refresh can be called with interactive, but search
    with non-interactive, then the search can fail to refine metainfo
    data with error "No such ref", because its internal flatpak cache
    was not updated.
