chore: Update a mock for tests

[dan437]

Description

The mock has been updated to be less specific, so that the mocked network response is used in more situations. This is meant to address a frequently failing flaky test (example: https://app.circleci.com/pipelines/github/MetaMask/metamask-extension/113905/workflows/1140e350-cf29-45ff-916e-6fa0f3befc67/jobs/4268755/parallel-runs/16)
