[MNG-6173] Test getProjects() and getProjectDependencyGraph()

Adds a test for checking that MavenSession.getProjects() contains the
projects being built and that MavenSession.getProjectDependencyGraph()
is set.

The fix for MNG-6173 changed the way these to properties are
initialised. This integration test verifies that the initialisation is
still correct.
