Bug: Issue with imagePullPolicy on a deployment

Hello,
I encountered a weird issue with a deployment manifest that is using a local image
```
Waiting for deployments to stabilize...
- deployment/ is ready. [2/3 deployment(s) still pending]
- deployment/: container 1 is waiting to start: :5b0737433ed8db461f77b1cd1f1247b656be55455ad43b64553d149d4bafa0b8 can't be pulled
- pod/: container 2 is waiting to start: :5b0737433ed8db461f77b1cd1f1247b656be55455ad43b64553d149d4bafa0b8 can't be pulled
- deployment/ failed. Error: container 1 is waiting to start: :5b0737433ed8db461f77b1cd1f1247b656be55455ad43b64553d149d4bafa0b8 can't be pulled.
1/3 deployment(s) failed

```

This is the deployment that was causing the issue :
```
apiVersion: apps/v1
kind: Deployment
metadata:
name:
spec:
replicas: 1
selector:
matchLabels:
app:
template:
metadata:
labels:
app:
spec:
containers:
- name: 1
image:
imagePullPolicy: Always
ports:
- containerPort: 80
...
```

When i remove the imagePullPolicy, its working, I stumbled upon this https://github.com/GoogleContainerTools/skaffold/pull/9495, so i assume this issue should not be happening

```
> skaffold version
v2.16.1
```
