Initial test cases for PGDOIDatabase

Include postgresql Driver in doi test scope

Test wouldn’t run without this.  This test needs to use postgres and
not the mock database manager

Forgot to include the query
Extra DOI format checking in queryExistingDOI

DOI.equals doesn’t check the url/internal identifier, so assuming that
equals would return false based on a different identifier was invalid
