fix(@angular/cli): remove the need to specify --migrate-only when `…

…--name` is used during `ng update`

This commit updates the behaviour of `ng update --migrate-only` to remove the need for `--migrate-only` option to be specified. `--migrate-only` will be set internally.

Before
```
ng update @angular/cli --migrate-only --name=migration-name
```

Now
```
ng update @angular/cli --name=migration-name
```
