    gkr: Backend: load_collections can have errors
    
    Make sure we also call the appropriate finish method of
    `SecretService::load_collections()`, as that at least tells us if
    something went wrong.
    
    Found out this snipped, as somehow the `Items` property showed an
    item that didn't exist as an object path. This made the loading of the
    whole collection fail, so I couldn't view the login keyring anymore in
    Seahorse, which is quite unfortunate.
