fix(StatusInput): ensure validator messages are rendered when validators return boolean values

There's two ways to signal that a validator emits invalidity on a control:

1. Its `validate()` method returns `false`
2. Its `validate()` method returns an object

Option 2) allows validators to supply the `errors` object with additional data.

Due to latest changes to `errorMessage` handling in validators, those messages
would not be rendered anymore if a validator returns simply `false` instead of an object.
The reason for that is because the code assumed that only option 2) is gonna happen.

This commit ensures that error messages a displayed in both options.
