Follow-up from "follow LHCb!2099"

The following discussion from !1682 (merged) should be addressed:

• QMTest log file parsing does not like it when counters change type:

@clemenci I think that more than a problem with parsing it's probably a problem with changing the type... the check detects a format in the reference and expects the same format in the output.

@cattanem OK, I'll provide an update of the references, but it would be nice if the test would give a missing/changed counter error rather than bomb out...
