Thanks for the report.

Nowadays the right way to configure this is to say just

  bootloader = "pygrub"

This will work with the packages I have prepared for Debian stretch
(aka testing).  But TBH I'm not sure that will work with the packages
in jessie.

Can you try that and let me know if it works ?

Thanks,
Ian.
