traverseiterator RPC server test is failing on fresh chain

[AnnaShaleva]

Current Behavior

traverseiterator RPC server test is failing if running on newly-generated basic chain:

The test passes on the old dump of basic chain.

Expected Behavior

Test should pass.

Steps to Reproduce

1. Regenerate basic chain with saveChain = true using TestCreateBasicChain.
2. Update related constants (testContractHash, deploymentTxHash and etc.) in pkg/services/rpcsrv/server_test.go.
3. Run make test, check the result.

Context

Discovered by @AliceInHunterland in #3560 (comment).

Regression

Basic chain wasn't regenerated for a long time. It's possible that we've changed something on the RPC server side or on the core side that affected SC iterator traversal process.
