Comment 8 for bug 2026319

IIUC the autopkgtest failure flags should be cleared by a retry with migration-reference/0 so I've requested these. This will effectively disable git-remote-hg's autopkgtests from being consulted for any future git SRU, but on balance against the effort in individually fixing or disabling that particular test and holding up this SRU, this seems OK to me. I think it's OK to fix the test case though and to hold it in -proposed to help with future git SRUs, if someone wants to do that.
