Date table re-generated in steps 2, 3 etc.

If we generate data in steps (-S 1, -S 2 etc.), the Date table is fully re-generated in each step. Let's make it only be generated by the first step.

Credit goes to @t3rmin4t0r in his fork for addressing this issue (although the way he does it is not exactly the same; I think mine is better.)

Need to revert this change; for TPC-H generation happens for step values beyond 1. So either we change that all uniformly or it shouldn't be changed in the first place.
