Fix incorrect assertion syntax in test_populate_data_quality_warning

[Copilot]

Addresses review feedback from #1737 regarding malformed assertion in test/test_database.py:101.

Changes

• Fixed assertion using comma operator instead of equality check:

  # Before: tests truthiness with misleading error message
  assert first_dqw.message, "Hello == World!"
  
  # After: tests actual equality
  assert first_dqw.message == "Hello, World!"

• Corrected expected value to match test fixture data ("Hello, World!" vs "Hello == World!")
