test: Remove obsolete test_refactor_suite.py

Removed test_refactor_suite.py as it is completely superseded by the
comprehensive test suite:

Reasons for removal:
- Broken: Import errors, cannot run
- Incomplete: Contains TODO comments, no actual assertions
- Overlapped: Functionality covered by test_multi_device_simulation.py
- Inferior: 1 broken test vs 20 passing comprehensive tests
- Wrong approach: Tried to run real BLE instances instead of using mocks
- Already excluded: Ignored in CI via --ignore flag

The multi_device_simulation test suite provides superior coverage:
- MockBLEComponents (5 tests)
- SimulatedBLENode (3 tests)
- TwoDeviceSimulator (6 tests)
- IntegrationScenarios (4 tests)
- Performance (2 tests)

This was leftover scaffolding from the driver abstraction refactor.
