s4-drs: Test situations for runtime constructed parentGUID

Includes the following verifications for the constructed parentGUID:
- Checks if it returns nothing when there is no parent object
- Ensures that attributes mentioned after the parentGUID
are returned correctly (this avoid a bug pointed out by Tridge
during sync constructed parentGUID development)
