Reuse existing EVM instance in interop calls

[codchen]

Describe your changes and provide context

Using new EVM instance for interop calls can cause discrepancies in behavior against ethereum. This PR changes the behavior to be reusing existing EVM instance, with an additional tweak which returns the latest sdk.Context from the evm instance to the wasmd message handler, so that there will never be a scenario where messages dispatched by a wasm call operate on different sdk.Context.

Testing performed to validate your change

existing integration test should still work
