Fix: #2749 bug "Can no longer delete permissions"

[erikn69]

Illuminate/Database/Eloquent/Model.php#L615-L619

public function newInstance($attributes = [], $exists = false)
{
// This method just provides a convenient way for us to generate fresh model
// instances of this current model. It is particularly useful during the
// hydration of new objects via the Eloquent query builder instances.

• newInstance was removed on Improve performance for hydrated collections #2749
• Closes Can no longer delete permissions returned by "findByName" #2758
