[10_6 backport] Define proper BS for 2018 premixing workflow if starting from scratch

[srimanob]

PR description:

To fix the bug of 2018 premixing wf if start from scratch. BS of 2017 was used. It seems normally, PdmV uses GS from StandardPU wf where BS is handled properly, so the issue has never been spotted. This is to keep the proper configuration of legacy release.

PR validation:

runTheMatrix.py --what premix -l 250200.18 --wm init
provides proper configuration

if this PR is a backport please specify the original PR and why you need to backport that PR:

Backport of #29401, to keep the proper configuration of Legacy release.
