    GeditDocument: fix bug when setting metadata
    
    g_file_info_copy_into() begins to clear @dest_info, and then copy the
    attributes from @src_info to @dest_info.
    
    So the previously loaded metadata in doc->priv->metadata_info were
    removed each time that gedit_document_set_metadata() was called (with
    the gvfs metadata). Now the new attributes are correctly copied, without
    removing the other ones.
