commit: use context manager with dirstateguard
When I wrote
5ac845ca059a (commit: don't let failed commit with
--addremove update dirstate (issue5645), 2017-07-31), Durham's
609606d21765 (rebase: use one dirstateguard for when using
rebase.singletransaction, 2017-07-20) had not yet landed, so I had to
write it in the old-fashioned way. Now that Durham's patch is in, we
can simplify by using a context manager.
