Steps to Reproduce

For VirtualMachine:

In nbshell

# ./manage.py nbshell
from virtualization.models import Cluster, VirtualMachine, VMInterface
cluster = Cluster.objects.get(name="cluster1")
vm = VirtualMachine(name="vm1", cluster=cluster)
vm.full_clean()
vm.save() #Saving vm to be able to add nic below

nic1 = VMInterface(virtual_machine=vm, name="nic1")
nic1.full_clean()
nic1.save()
vm.save() # with this will trigger the bug

2.Check GUI -> Virtual Machines -> Configure Table -> Add Interface Columns -> It shows '0'.
3.Check GUI -> Virtual Machines -> vm1 -> Interfaces tab shows nothing, -> in interface tab, nic1 is created.

For Devices:

in nbshell

# manage.py nbshell
from dcim.models import DeviceRole, DeviceType,Site,Device,Interface
role=DeviceRole.objects.all()[0]
dt=DeviceType.objects.all()[0]
site=Site.objects.all()[0]
dev1=Device(name='dev1',role=role,site=site,device_type=dt)
dev1.full_clean()
nic1=Interface(name='nic1',device=dev1,enabled=True,)
nic1.full_clean()
dev1.save()
nic1.save()
dev1.save()  # with this will trigger the bug

check GUI -> Devices -> Configure Table -> Add Interface Columns -> It shows '0'.
check GUI -> Devices -> dev1 -> Interfaces tab shows '1' -> in the Interfaces, nic1 is created.

Expected Behavior

For VirtualMachine:
Interface Column should shows '1' instead of '0'
Interface Tab should shows '1' instead of '0'

For Devices:
Interface Column should shows '1' instead of '0'

Observed Behavior

The interface_count is not synced from interfaces.count() as it should after objects.save(), interface tab does not show the correct interface count.
