    appinfo: Do not override system default handler with less specific one
    
    We were considering explicitly configured defaults for parent types
    after we already got results for the specific type we're interested in.
    
    This resulted in the explicit default for text/plain to override all
    system defaults for subtypes of text/plain, for example. The explicit
    default should not apply to subtypes that have a system default.
