    core: initialize caps filter to none.
    
    Sync with the comment above telling the filter is to be initialized
    to none.
    
    Partially revert commit  5b88159eaa8d06a5f17c092cbb69b79e62d48f2b
    
    The issue is that grl_upnp_source_get_caps set the search and browse
    caps to FILTER_ALL if filtered is supported and do not touch them
    otherwise. But grl_caps_new instantiate a caps with filter initalized to
    FILTER_ALL ... so grl_upnp_source_get_caps always returns caps with
    FILTER_ALL .
    
    Fixes browse vs search for grilo plugin upnp at least against servers
    that has no or incomplete search capabilities.
