Fix tests which are failing in @vue/test-utils 1.x" due to search by name

What does this MR do?

Related issue: #240756 (closed)

VTU 1.x will deprecate .find() by passing name, i.e. .find({ name: 'foo' }) and in certain cases it fails in such search (not just throwing deprecation warning)

This MR refactors such .find instances from our code base
