rebase: --abort doesn't strip away the target changeset (issue2220)

When a changeset is skipped, rebase keeps the previous target as next
target and if the skipped cset is the first one, the recorded target is
actually the original target.
--abort did not detect this situation but simply stripped away the cset.
