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
