Update repository unit tests to have Project fixture and do additional Project testing

[QMalcolm]

resolves #9870

Problem

Writing unit tests is hard, so we're trying to build more fixtures that are common needs. The Project fixture is a commonly needed fixture, so adding it makes future writing of unit tests easier

Solution

Create a Project fixture in unit tests.
