    owncloud: Set the correct port number in GoaFiles:Uri
    
    Thing is that soup_uri_set_scheme has the side-effect of setting the
    port to the default port for the specified scheme. Therefore when we
    change http(s) to dav(s) we lose the non-standard port, if any. We
    need to save the original port number and set it again.
    
    Also, it is cleaner to use a temporary copy than modifying the
    original object. Unintended side-effects like this will be contained
    within the function and not be leaked to the caller.
