perf-unbundle: do a quick and dirty fix to make it run on more commit
Without this change, the perf commands fails within the
f67741e8264b::18415fc918a1 range (boundary excluded).
Check inline comment for details.
With this fix, the command is able to run on this range, with a slightly
different behavior (as no revset is "uninlined"). However this is still much
better than not being able to run anything in this range. Especially because
that range do see some performance regression for unbundle.
