Remove all database URLs & creds from project
 - All tests that use the database now extend `AbstractServiceTest`
 - The (sql2o) `Connection` used by the tests resides in `AbstractServiceTest`
 - default-properties.xml (src/test/resources) now takes maven properties from ~/.m2/settings.xml for the DB URL & creds.
The a new connection should be acquired for each test
 - Also, only rebuild the unittest database once, at the beginning of the test suite
Shore up functional tests.
 - `PaymentResourceFunctionalTest` fails occasionally.  Specifically the transaction fails.
