Fix: Add missing expectations in IpWidget test

[Himess]

This PR adds missing expect statements to the IpWidget test. Previously, the test only rendered the component without validating its behavior or output. This change ensures the component behaves as expected and aligns with the project's testing standards.

Why this change?

The test suite in related repositories follows a standard of including expect statements to validate functionality. This PR brings the IpWidget test in line with that standard by adding expectations to ensure its behavior is properly validated.

References:

1. attachLicenseTerms Test (protocol-core-v1)
2. Permission Test (protocol-core-v1)
3. TotalLicenseTokenLimitHook Test (protocol-periphery-v1)

These references demonstrate similar standards of using expect statements for validation across different parts of the project. This PR ensures consistency in the testing approach.
