[BUG] git pull with pull.rebase and rebase.autoStash is not working anymore in 2.16

[Dimitriy <dimitriy.ryazantcev@gmail.com>]

Looks like regression in 2.16.
Worked fine before update.
Seems like git stash is not always working.
Any ideas?

git version 2.16.0.windows.2

true

$ git config rebase.autoStash
true
