DateInterval::createFromDateString does not throw non-relative items are present

### Description

The following code:

```php
<?php
$d = DateInterval::createFromDateString('next weekday 15:30');
?>
```

Resulted in no warning.

But I expected a warning telling me that the `15:30` was going to be ignored.
