Bug#400342: lintian: root/reporting/harness -i does not work

[Bill Allombert <ballombe@debian.org>]

Package: lintian
Version: 1.23.26
Severity: normal

Hello Debian Lintian Maintainers,

root/reporting/harness -i perform a full update not an incremental update.

I tracked the issue to the call to lintian --setup-lab. For some
reason this call delete the history files of the last run.

Please find the patch I use to work around the issue.

Cheers,
