* evm: fixed commented out simulations, pubsub, and handler tests fixes #640 simulations are very basic: they can be built and executed, but they don't generate any EVM-related transactions yet. (It should be a matter of adding simulation-related code to the modules + potentially extra helpers to the simulation.) handler tests miss some extra assertions due to changes in the return values snapshotting logic (ADR-001 and ADR-002). Besides the test suites identified in the audit, there's also "importer_test.go" which wasn't yet fixed. (it'd require major rewriting + extra test resources) * gofumpt
