Fix remaining integration test failures

- Fix test_app_activity_functions.py SQLAlchemy database issues:
  - Reinitialize db with test app config before creating tables
  - Store and restore original database URI in tearDown
  - Add try/except around drop_all in tearDown

- Fix test_activity_integration.py attempts increment test:
  - Remove next_section_and_step from incorrect transition
  - When next_section_and_step is specified, code navigates without incrementing attempts
  - Transition should only have counts_as_attempt without navigation to increment and stay on same step
  - This matches the actual behavior: navigation happens immediately when specified
