Aura: Do not verify on state import (paritytech#13058)

* Aura: Do not verify on state import When we import the state, we can not fetch authorities to verify the seal etc. So, we can directly skip any verification. * Skip checks as well for gap sync * Update client/consensus/aura/src/import_queue.rs Co-authored-by: André Silva <[email protected]> * Review comment Co-authored-by: André Silva <[email protected]>
