Remove dependency of tests on scripts

[filmakarov]

Fix this #223

---

PR-Codex overview

This PR focuses on refactoring the TestHelper contract to streamline the setup of the ENTRYPOINT address, replacing the instantiation of HelperConfig with a new setupEntrypoint function that handles both test and mainnet scenarios.

Detailed summary

• Removed the import of HelperConfig in TestHelper.
• Added a setupEntrypoint function in TestHelper to initialize ENTRYPOINT.
• The setupEntrypoint function checks the chainid and sets ENTRYPOINT accordingly.
• The constant MAINNET_ENTRYPOINT_ADDRESS is defined in both HelperConfig and TestHelper.
