    flatpak: move to gitlab.gnome.org GMime version
    
    duplicate_mailbox() unit test fails since this commit:
    https://github.com/jstedfast/gmime/commit/4a80ae527df9aa36fe50fac0878207a31d4d6b72
    
    The commit is ok because it respects RFC 5322: 1 max From/To/Cc/Bcc
    header.
    
    We can't fix the unit test without breaking Ubuntu/Fedora builds so just
    use same version.
