test_course_created_event() is doing some 'interesting' tests which directly invoke IMS Enrolment plugin.

We need to look at this and decide:

• is the test actually worthwhile having; and
• does it have to use IMS Enterprise plugin directly, or can we find a different way to test it.

From my read of this test, the whole second part of the test is entirely superflous and should be removed. but need to confirm this.
