The `NgControlStatusGroup` directive is shared between template-driven and reactive form modules. In cases when
only reactive forms module is present, the `NgControlStatusGroup` directive is still activated on all `<form>`
elements, but if there is no other reactive directive applied (such as `formGroup`), corresponding `ControlContainer`
token is missing, thus causing exceptions (since `NgControlStatusGroup` directive relies on it to determine the
status). This commit updates the logic to handle the case when no `ControlContainer` is present (effectively making
directive logic a noop in this case).
Alternative approach (more risky) worth considering in the future is to split the `NgControlStatusGroup` into
2 directives with different set of selectors and include them into template-driven and reactive modules separately.
The downside is that these directives might be activated simultaneously on the same element (e.g. `<form>`),
effectively doing the work twice.
