`RegistrationViewResourceFunctionalTest`s now working
important changes!
 - `TestSqlConnectionProducer` now returns a wrapped `Connection` called `TestSql2oConnection`
 - this specialized connection for classes prevents `Connection.commit()` and `Connection.rollback` being called from `TransactionalResource`
 - the creation of a `TestSql2oConnection` also defaults autoCommit = false and rollbackOnException = false .
 - add container utility class collections for resource tests
 - add container utility class collections for anything that uses a conference service
