BISERVER-7280 Get Jobs List checking if logged user is Admin 

- Updated jobs call to include a check like canAdminister on FireResource;
- Updated user name used to filter jobs. Currently is only checking via Pentaho session because previously it wasn't matching using SecurityHelper.getInstance().getAuthentication().getName();
- Moved canSchedule call from FileResource (bad location) to SchedulerResource. Consequently, calls on user-console project were updated to this new url.
