Bug 550814 - [Data Template] References to Ecore should use run-time URIs

- fix the Template::instance reference to use the run-time URI for the EObject class instead of the development-time URI
- reload the genmodel which now no longer needs to reference Ecore genmodel and re-generate the package metadata accordingly
- add a JUnit test in a new generated test fragment
