[BUG]: ORM infinite save loop

[rudiservo]

Describe the bug
The Model::save has no checks if a model has been called to be saved before, this can cause a infinite save loop.

Steps to reproduce the behavior:

$customer = Customers::findFirst();
$invoice = new Invoices();
$invoice->customer = $customer
$customers->invoices = [ $invoice ];
$customer->save();

Expected behavior
it is expected not so run save on the model that has already been called to saved.
