Add test for setTitleMaxLines in SelectorWithWidgetPreference 

Adds a unit test to verify the behavior of the `setTitleMaxLines` method.

The test ensures that calling `setTitleMaxLines` updates the underlying value and that the change is reflected in the title TextView's `maxLines` property after the view is rebound.
