TRUNK-4436: Drug orders for different formulations of the same concept

This is a fix for https://issues.openmrs.org/browse/TRUNK-4436
If you add @shoulds to a method, then try not to write these test methods manually, you need to use the test generator plugin at https://wiki.openmrs.org/display/docs/Generate+Test+Case+Plugin otherwise OpenmrsTestsTest.shouldStartWithShould will fail like it is doing right now, i will clean it up
