Use the class queue_name and project for tests
Use the class queue_name and project for tests

Marker's test used a local queue_name instead of the one defined in the
base class. This caused some tests to fail because the ran on a no clean
database.

The patch makes the test use the queue_name and the project defined in
the class.
