[11.x] Fix validator return fails if using different date formats

[mrvipchien]

This PR fix the date validator if the validator has diff date formats like this:

[
    'from' => 'date|before:to|date_format:Y-m-d',
    'to' => 'date|date_format:Y-d-m|after:from',
]

checkDateTimeOrder() only use the first format.
