DumpMachine does not produce console output when running from Q# unit tests

[tcNickolas]

Describe the bug

DumpMachine called from Q# unit test (defined using @Test attribute) does not print program state.

To Reproduce

Superposition kata uses DumpMachine to print expected and actual states for each exercise. You can run dotnet test on that project to see that there are no state dumps after "The desired state" and "The actual state" (https://github.com/microsoft/QuantumKatas/blob/main/Superposition/Tests.qs).

Expected behavior

Program state is printed in the unit tests.

System information

• OS: Windows 11
• .NET Core Version: 6.0.401
• QDK 0.25.228311 and 0.25.218240 (used to work a year ago)

Additional context
When the same code is invoked from Q# Jupyter Notebook frontend, state dumps are produced successfully.
