Increase coverage in projects generated with rx_bloc_cli

[DDavidPrime]

Projects generated with the rx_bloc_cli currently have a select number of unit tests which result (with all flags enabled) to about 6% in code coverage. Add unit tests to increase code coverage to at least 50%.

ACs:

• [ ] Add unit tests for existing functionality in the rx_bloc_cli generated projects
• [ ] The minimum code coverage should be at least 50 for projects with all flags enabled
  • [x] Golden tests for the login form
  • [ ] Analytics bloc unit tests
  • [ ] lib_auth unit tests
  • [ ] lib_permissions unit tests
  • [ ] lib_realtime_communication uni tests
  • [ ] common_ui_components golden tests in the base brick
  • [ ] extensions unit tests in the base brick
  • [ ] error_mappers unit tests in the main brick
  • [ ] PIN golden and unit tests (Low priority)
• [ ] Update run_app_tests.yaml github workflow in generated projects to reflect the minimum code coverage

I wasn't able to push the changes and since I'm in PTO, I move the task in To Do.
