My organization has been struggling with this issue for ~6 months, and the fix Christian describes in comment #44 resolved this problem for us. I used the bionic-updates instead of xenial-updates, and enterprise wide, the grub rescue console does NOT display anymore when loading the PXE menu. Monday morning, I will be the HERO at the office! All the thanks to this thread and the dedicated team who resolved this bug.
