Fix the secure Thunderbird autoconfig wizard patchset
Something is wrong with the secure autoconfig wizard in 60.5.1-1~deb9u1.0tails1: #16422 (comment 12982). Initial testing results suggest that there is a bug in Thunderbird itself and another one in our patchset.
It might be that a newer Thunderbird (60.6 or 66) would fix it.
