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.
