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.

Everywhere including examples, external interop APIs, bindings generators
code and in other valuable places. A couple of `interface{}` usages are
intentionally left in the CHANGELOG.md, documentation and tests.
1. `System.Contract.CallNative` expects version on stack.
2. Actual method is determined based on current
instruction pointer.
3. Native hashes don't longer depend on NEF checksum.
