58ab3b5ad1 core: get native nep17 balance from contract storage
Not from DAO's items with storage.STNEP17Balances prefix, because
changes are reflected there only after notifications processing. And
this happens only after the transaction script is executed, but there
might be cases when we need to get the balance that was updated
earlier during the same transaction processing.

Affects storage dumps.

edfca68a17 rpc: refactor invokecontractverify
In `(c *Client) AddNetworkFee` we define network fee for contract
witness verification via `invokecontractverify` RPC call, and that's the
initial purpose of this RPC method. But it was not implemented
correctly. It used `System.Contract.Call` instead of beheiving like
`initVerificationVM`.

During real contract witness verification the whole contract's script is
loaded into VM, and then we jump to the `verify` method. Thus, to define
exact contract verification price, we should act like this (and not just
perform `System.Contract.Call` of `verify` method).

Tests are added.

This bug is the reason of adding extra GAS (c.notary.extraVerifyFee) to
pre-calculated value in

2. Actual method is determined based on current
   instruction pointer.
3. Native hashes don't longer depend on NEF checksum.
