block: add PrimaryIndex to the stack item of block

This is a bad one.

9 fields vs 10, notice the primary index right after the block number.

Back when ac527650eb initially added Ledger I've
used https://github.com/neo-project/neo/pull/2215 as a reference and it was
correct (no primary index). But then https://github.com/neo-project/neo/pull/2296
came into the C# codebase and while it looked like a pure refactoring it
actually did add the primary index as well and this wasn't noticed. It wasn't
noticed even when 3a4e0caeb8 had touched some
nearby code. In short, we had a completely wrong implementation of this call
for more than three years. But looks like it's not a very popular one.
