test(aio): remove compileComponents from all tests

By reflex we began all component tests with an async `beforeEach` that called `compileComponents`.
In at least one case (`live-example.component.spec.ts`) that led to the `it` tests being async as well.
There is no need to call `.compileComponents` because CLI web pack + plugin inlines all templates and styles.
While `.compileComponents` was harmless, it added complexity and distraction which we should not inflict on future readers and testers.
