[LesnyRumcajs]

This reverts commit d4408ae.

Summary of changes

Changes introduced in this pull request:

• reverts fix: fix incorrect MinerGetBaseInfo #4617 due to Consensus error when syncing from an old snapshot #4626,
• while technically the PR above is correct (it provides the right RPC responses), our shims are lagging behind (based on FVM3 without support for NiPoRep), causing consensus errors. I'd rather we revert for now so that the daemon doesn't fail.
