[5.0] Cast boolean values to appropriate string

[browner12]

boolean true cast to a string is "1", while boolean false cast to a string is an empty string.

If you try to select an element that your model has set as false it will most likely fail because the value of your <option> will not be an empty string

class Site extends Model
{
    $casts = [
        'enabled' => 'boolean',
    ];
}

$browser->select('enabled', $site->enabled);

 <select name="enabled">
    @foreach(['no', 'yes'] as $key => $option)
        <option value="{{ $key }}">{{ ucwords($option) }}</option>
    @endforeach
</select>
