add course bug

[robertocapannelli]

It is possibile to add new course even if the course is not presente in the database. It could be correct but before I need to have an object course into the database. For example a solution could be to ask to the user to add the new course if not present in the database

As we said, we change the flow:
home->add schedule->add course if not exists->home
