job: Don't mark as redundant if deps are relevant

In the steps given in #13850, the resulting graph looks like:

    C (Anchor) -> B -> A

Since B is inactive, it will be flagged as redundant and removed from
the transaction, causing A to get garbage collected. The proposed fix is
to not mark nodes as redundant if doing so causes a relevant node to be
garbage collected.

Fixes #13850
