Log UUID when ValidateCollections detects a UUID in SchemaVersion 3.4

In MongoDB 3.6 collection validation, we check that UUIDs are present when featureCompatibilityVersion is 3.6 and not present when featureCompatibilityVersion is 3.4. If a UUID is erroneously present when FCV is 3.4, we should log what the UUID is to more easily trace the offending collection in the logs.
