create a _fetch_status function in the docdata adapter to make test mocks easier
- change donaton api test to not extend OrderApiTestCase (setUp was including unused code)
- mock the check_status_psp method on ManageOrderDetail which was trying to fetch a status update from the psp (not needed in this test class)
