TODO: When deleting is available, test deleting uploaded files`

test.py was changed such that the database being used is test_xcontent
course_helpers.clear_courses now calls contentstore().fs_files.drop() such that all content is removed and the databse is started afresh in the same manner as the modulestore

Also modified the create_course method in common to allow for the possibility to access the course name and etc. from other files.
