    tests: Perform SELECT DISTINCT to find out resource URN
    
    The test checks that the resource URN is single, which is good, but
    doesn't account for the same URN being returned through multiple graphs.
    Use SELECT DISTINCT so the check remains valid if the resource is
    scattered in different graphs.
