Fix "Can't set model as property if it hasn't been persisted yet" after deleting a record.

I got error "Can't set model as property if it hasn't been persisted yet" when deleting a record. I'm trying to find the solution in discord but no response about this.

So in Livewire 3 it seems we must persist the property. this PR solve my issue.
