[Test] Enable bypassed e2e test cases for appside mempool

## Problem

Bypassed e2e test cases for appside mempool should be enabled.

## Problem Details

There is test case that is intentionally bypassed. (https://github.com/cosmos/evm/pull/580#discussion_r2345194816)
It is because, appside mempool is not compatible with geth. (https://github.com/cosmos/evm/issues/590)
Currently, because that issue was fixed (#590 ), bypassed test cases should be enabled.

## Completion Criteria

- enable bypassed test cases
- all test cases pass

Locate the intentionally bypassed appside mempool end-to-end test cases and review the context in issue #590 and the linked pull request discussion. Enable the cases, then run the relevant e2e test suite; done means all test cases pass.
