Fix ImportError for CommissionDeviceTest in test_harness_client

CommissionDeviceTest has been moved from matter.testing.commissioning
to matter.testing.CommissioningPreTest in the Matter SDK. The old path
no longer exports this symbol, which causes --get-test-info to fail and
the Python test list to be empty in the UI.

Fixes #981
