Subject: [PATCH] git rebase --abort: always restore the right commit

Previously, --abort would end by git resetting to ORIG_HEAD, but some
commands, such as git reset --hard (which happened in git rebase --skip,
but could just as well be typed by the user), would have already modified
ORIG_HEAD.

Just use the orig-head we store in $dotest instead.

[jc: cherry-picked from 48411d and 4947cf9 on 'master']
