don't switch from 'Thread Date' to 'Date' when clicking column header

When sorting by Thread Date, make clicking the Date columm header not switch to sorting by
Date, but remain sorting by Thread Date, just toggling between ascending/desending, and
maintaining the previous behaviour when sorting by Date.
