    google: Remove redundant g_strdup for gdata_entry_get_id results
    
    The additional g_strdup() was needed to prevent segfaults caused by the
    following issue in libgdata: https://gitlab.gnome.org/GNOME/libgdata/issues/31.
    
    TODO: Bump the libgdata dependency accordingly before merge.
