JobScheduler reporting interface should use the file hibernate.cfg.xml as default.

Desription
The JobScheduler reporting interface uses an own configuration file for the database connection. The file is {{hibernate_reporting.cfg.xml. }}

Desired behaviour
The reporting interface has its own configuration file because it should be possible to store the reporting data in another database as the JobScheduler database. But in the case that the same database is to be used the file hibernate_reporting.cfg.xml is a one to one copy of hibernate.cfg.xml. Therefore the default file should be hibernate.cfg.xml.
