    GDesktopAppInfo: fix default app logic
    
    We use "tweaks" structures to track how a particular directory impacts
    the list of added, removed and default applications.  We maintain this
    set of tweaks for each directory, in a hash table, keyed by unaliased
    mime type name, in order to facilitate fast lookups.
    
    A typo in the logic for creating and maintaining the uniqueness of these
    structures was causing the default app to be selected incorrectly from
    time to time.  Fix that.
