From: Phillip Wood <redacted>
Aborting a rebase stated with 'git rebase <upstream> <tag-object>'
should checkout the commit pointed to by <tag-object>. Instead it gives
error: update_ref failed for ref 'HEAD': cannot update ref 'HEAD':
trying to write non-commit object
710d743b2b9892457fdcc3970f397e6ec07447e0 to branch 'HEAD'
This is because when we parse the command line arguments although we
check that the tag points to a commit we remember the oid of the tag
and try and checkout that object rather than the commit it points
to. Fix this by using lookup_commit_reference_by_name() when parsing
the command line.
