🐛 Permissions mutator should not try to save the role

[andrzejkupczyk]

Since the setPermissionsAttribute() mutator tries to save the model, it is not possible to create a new role along with permissions using the create method ("Integrity constraint violation: 1062 Duplicate entry"). In my opinion mutators are not meant to communicate with database at all.

This is an example of code that does not work:

Role::create([
    'name' => 'Administrator',
    'slug' => 'admin',
    'permissions' => [
        'viewNova',
    ],
]);

There are at least two solutions. You could resign from saving the model within the mutator or guard "permissions" attribute (disable mass assignment).

Great package btw. Thank you 🏅
