Update HtmlTest.php

Pull Request Description
Changes:
Enhanced the selection check in Html::renderSelectOptions:
Added a condition to handle cases where $selection is an object that possesses a value property.
Rationale:
The primary goal of these changes is to provide improved flexibility in the types of data that can be passed as $selection and to streamline the comparison logic for better maintainability and clarity.

Test Additions:
Introduced a new test, to verify the behavior when $selection is an object with a value property.
