Ignore DataFault incidents in ref validation
The following line is a frequent cause for reference updates and conflicts in the latter.
DataOnDemandSvc INFO Handled "DataFault" incidents: 100/0/102551(Alg/Node/Total).
With this MR, changes in the counts will not be considered a failure and will not be part of future commited refs.
Given that we are moving away from on demand data creation I think it's fine to ignore this. It may still be an interesting proxy for performance related to TES accesses (it will remain in stdout).
