verify: avoid spurious integrity warnings in verbose mode (issue6172)

The issue seems to revolve around renames in filtered commits, and only occurred
in verbose mode.  The problem occurs in the `# check renames` stage, around line
577.  Without using the unfiltered repo, this test would have printed:

    $ hg verify -v
    repository uses revlog format 1
    checking changesets
    checking manifests
    crosschecking files in changesets and manifests
    checking files
     foo@25: checking rename of 71ec0570c325: filtered revision '25'
     foobar@26: checking rename of 1b549296015b: filtered revision '26'
    checked 28 changesets with 16 changes to 11 files
    2 integrity errors encountered!
    (first damaged changeset appears to be 25)

  $ hg init a
  $ cd a
  $ hg init b
  $ echo x > b/x

Should print nothing:

  $ hg add b
  $ hg st

  $ echo y > b/y
  $ hg st

Should fail:

  $ hg st b/x
  abort: path 'b/x' is inside nested repo 'b'
  [255]
  $ hg add b/x
  abort: path 'b/x' is inside nested repo 'b'
  [255]

Should fail:

  $ hg add b b/x
  abort: path 'b/x' is inside nested repo 'b'
  [255]
  $ hg st

Should arguably print nothing:

  $ hg st b

  $ echo a > a
  $ hg ci -Ama a

Should fail:

  $ hg mv a b
  abort: path 'b/a' is inside nested repo 'b'
  [255]
  $ hg st

  $ cd ..
