Remove SDATE=CDATE IAU block in NCO config.base (#963)

- Remove the block in config.base.nco.static that checks if CDATE=SDATE and turns IAU settings to 0.
- This block is not needed in operations and causes issues in pre-implementation developer testing when starting a new warm-started parallel with wave restarts.
