Fill assigment model with not fillable column

[jamesRUS52]

Hi, all!
Now, when trying to mass assigment with column not in fillable list, we get ignored value, but it save silently with default database value. It's not clearly at all and may make logical errors with data.

E.g.
$filable = ['column1'];
database schema like
create table tab column1 int, column2 int default 0;
TabModel::create(['column1'=>1, 'column2'=>1]);
The record in database will be column1 = 1 coumn2 = 0
and no any error has occured. Its not clear at all. The developer should every time check fillable in model.
My suggest is to chenge $this->totallyGuarded() check to throw Exception if fillable list fill or not in

public function totallyGuarded()
    {
        return count($this->getFillable()) === 0 && $this->getGuarded() == ['*'];
    }
`

public function fill(array $attributes)
{
$totallyGuarded = $this->totallyGuarded();

    foreach ($this->fillableFromArray($attributes) as $key => $value) {
        // The developers may choose to place some attributes in the "fillable" array
        // which means only those attributes may be set through mass assignment to
        // the model, and all others will just get ignored for security reasons.
        if ($this->isFillable($key)) {
            $this->setAttribute($key, $value);
        } elseif ($totallyGuarded) {
            throw new MassAssignmentException(sprintf(
                'Add [%s] to fillable property to allow mass assignment on [%s].',
                $key, get_class($this)
            ));
        }
    }

    return $this;
}

`

What do you think about it?
