Fix CI failures and update MSSQL to stable 2019 version

- Fix getSchemaFromBranch to handle missing files in base branch gracefully
- Use empty baseline schema when file doesn't exist in main branch
- Update MSSQL to stable 2019-CU32-ubuntu-20.04 version (used for sqldef development)
- Fix sqlcmd paths for MSSQL 2019 version
- Rebuild dist/index.js with all fixes
