revlog: test possible read race condition with splitting

This is currently working fine, but could break with another approach (for
example, with the one we are about to use in the next changesets…)

So we make sure the case is covered.

Set up

  $ hg init repo
  $ cd repo
  $ echo a > a
  $ hg add a
  $ hg commit -m a

Try to import an empty patch

  $ hg import --no-commit - <<EOF
  > EOF
  applying patch from stdin
  abort: stdin: no diffs found
  [10]

No dirstate backups are left behind

  $ ls .hg/dirstate* | sort
  .hg/dirstate
