Migration from pre summer version leads courses and course templates with out title

[jamo]

and thus fails all updates to course.

The fix can be easily applied via console:

Course.all.each do |course|
    course.course_template.update_attributes(title: course.name.humanize)
    course.update_attributes(title: course.name.humanize) 
end

We should either add a new migration just to update these fields and make sure not to rewrite these or just find out and fix the migration which failed to do it...
