fix: Make python test failure with compile-time log threshold more in…

…formative (#1315)

If `ACTS_LOG_FAILURE_THRESHOLD` is set, a compile time threshold is
enabled and `setFailureThreshold` throws an exception. The python tests
assume this call to `setFailureThreshold` always works. This PR prints an informative error message about what to do about this, but reraises the exception.
