fix(@angular/cli): avoid redirecting @angular/core in Angular migrations

Browse Source 
Files should not redirect `@angular/core` and instead use the direct dependency of the `@schematics/angular` package. This allows old major version migrations to continue to function even though the latest major version may have breaking changes in `@angular/core`.
