fix(tests): simplify ListView edit test for known component bug

The ListView EditItemTemplate doesn't visually swap templates when
EditIndex changes (pre-existing bug). The ItemEditing callback fires
correctly and updates page state. Changed test to verify the callback
fires (status text changes to 'Editing') instead of asserting DOM
template swap (Update/Cancel buttons).

Tracked as a separate component issue to fix.
