SD2-727 - Null reference exception on running unit test. On running the test a second time the LoadAssemblyList method was invoking the callback without using the SafeThreadAsyncCall which meant the UpdateProjectTitles method was not being called until after the SelectTest call. The SelectTest method was then unable to match the project name with any node in the treeview.
