Webhook prechange snapshot missing when primary IP assigned or unassigned

[AesoSpadez]

NetBox version

v3.5.1

Python version

3.10

Steps to Reproduce

1. Create a webhook - Content type DCIM > Device, events Updates, any URL, and the rest blank/defaults.
2. Create a device (and all the prerequisite objects: Site, Role, Manufacturer, Type) - All defaults
3. If no interfaces on the device type, add one.
4. From the interfaces view of the device, add an IP address to the new interface - Check the 'Make this the primary' box.
5. Go to the admin portal, find the webhook in the finished or failed jobs lists of the default queue.

Expected Behavior

The value of the prechange key of snapshots should have the prechange object data.

Observed Behavior

The value of the prechange key of snapshots is None.

I'm pretty sure parent.snapshot() should just be added after L360 here:

netbox/netbox/ipam/forms/model_forms.py

Lines 354 to 374 in 0ad88e2

	def save(self, *args, **kwargs):
	ipaddress = super().save(*args, **kwargs)
	# Assign/clear this IPAddress as the primary for the associated Device/VirtualMachine.
	interface = self.instance.assigned_object
	if type(interface) in (Interface, VMInterface):
	parent = interface.parent_object
	if self.cleaned_data['primary_for_parent']:
	if ipaddress.address.version == 4:
	parent.primary_ip4 = ipaddress
	else:
	parent.primary_ip6 = ipaddress
	parent.save()
	elif ipaddress.address.version == 4 and parent.primary_ip4 == ipaddress:
	parent.primary_ip4 = None
	parent.save()
	elif ipaddress.address.version == 6 and parent.primary_ip6 == ipaddress:
	parent.primary_ip6 = None
	parent.save()
	return ipaddress

Open for contributors, otherwise I'll take it when I get the time.

I've been meaning to get started contributing anyways and this seems about as straight-forward a change as one could hope for. I can take a shot at a PR if you want to assign the issue to me.

Sounds good @AesoSpadez assigning it to you.
