Use ErrorLog instead of InfoLog in InstanceBase::ConsumedError

Printing to stdout actually impacts Web Tests results which
makes managing expectations difficult, especially if logs
change.

Change InfoLog to ErrorLog:
 1) because this is ConsumedError, after all
 2) until we figure out if we can make Web Tests ignore stdout
