Multi-value wildcard doesn't work when dimpaths contain repeated names #43

A filtered dataset had inconsistent constrained values across tables. The problem turned out to be that the constraint ignored one of the tables because it was using a multi-value wildcard. Switching to a single-value wildcard fixed it.
