fix(@schematics/angular): remove compileComponents from component test schematic

cexbrayat · angular-robot[bot] · commit 202e9a50f62b · 2023-03-24T18:30:26.000Z
`compileComponents` is not necessary when using the CLI (as the templates are inlined) and just adds boilerplate code. So we can remove it from the test schematic and make it independent from `async/await` (only place we would have it in the CLI generated code, and in most Angular apps).
