Issue description

Hi,

The latest version of WinterCMS is affected by an issue that prevents values returned by mutators to be persisted to the database. I read the SettingsModel behavior code and it seems that model $attributes are mistakenly overwritten by "original" values.

Steps to replicate

1. Create a Settings model.
2. Implement a mutator and return a different value for that form field.
3. Read the persisted value.

Workaround

Apparently the only solution is to override the beforeSave() method inside the settings model and to manipulate the JSON contained into $this->attributes['value'] by first deserializing it and then serializing it back.

Example:

protected function beforeSave()
{
	$fields = json_decode($this->attributes['value'], true);
	$fields['token'] = Crypt::encrypt($fields['token'] ?? '');
	$this->attributes['value'] = json_encode($fields);
}
