Testing needs a major refactor. Some things to look out for and fix:

• Integration testing should all be in /tests/integration
• We should move all of the tests which use the example app (evmd) into the evmd module so that we can re-create a go.mod and make it easier for quick setup of a cosmos evm chain. This will prevent the circular dependency between evm and evmd.
• Contracts that are only used for testing should be in a test or testutil folder
• All non-unit tests should be at the root /tests folder.
