    gs-plugin-appstream: Ignore refine for apps with no ID
    
    It can happen a plugin (in my case PackageKit) returns apps for update, which do
    not have set their ID. Trying to fins such app in an XbSilo resulted in an error:
    
       failed to process component/id[text()='(null)']: cannot parse text or number `null`
    
    which prevented the Updates page to show anything. Ignoring such apps does not
    influence the System Updates, these bare packages are part of it too.
