SSDM-11550 : Personal Access Tokens (PAT) - hopefully fix a problem where PAT DAO does not have access to Hibernate transaction due to a missing transactional proxy; the proxy for DAO cannot be created as initialization of the transactional beans is not yet finished at that point; for some reason this problem only occurs when openBIS is run from an installer (works fine when run from IDE); as transactional beans require DAO factory and DAO factory references PAT DAO hopefully separating PAT DAO from DAO factory should help (DAO factory gets created first, then transaction beans, then PAT DAO)
