Skaffold dev fails when user cannot list deployments at cluster scope

### Expected behavior

Running **skaffold dev** should work without issue if I have the required permissions on the deployed namespace

### Actual behavior

Skaffold complains about missing permissions at cluster level to check the deployement, whereas it should only check the it at namespace level

### Information

- Skaffold version: 1.28.1
- Operating system: Windows10 + WSL2
- Installed via: Homebrew
- Contents of skaffold.yaml:

```yaml
apiVersion: skaffold/v2beta19
kind: Config
metadata:
name: pricing.proxy.cron
build:
artifacts:
- image: pricing.proxy.cron.build
docker:
dockerfile: build.dockerfile
buildArgs:
AssemblyVersion: 1.0.0.0
Version: 1.0.0
- image: pricing.proxy.cron
requires:
- image: pricing.proxy.cron.build
alias: BUILD_IMAGE
docker:
dockerfile: cron.dockerfile
buildArgs:
AssemblyVersion: 1.0.0.0
Version: 1.0.0
tagPolicy:
gitCommit:

useBuildkit: true
deploy:
helm:
releases:

namespace: dev
artifactOverrides:
image: pricing.proxy.cron
setValues:
image.repository: pricing.proxy.cron
replicaCount: 1
imageStrategy:
helm: {}
```

### Steps to reproduce the behavior

1. Make sure to have no namespace defined in kubeconfig
```yaml
- context:
# NO NAMESPACE HERE
cluster: dev_cluster
user: dev_user
name: dev
```
2. skaffold dev -f .\skaffold.cron.yml

```
Helm release local-pricing-proxy-cron not installed. Installing...
NAME: local-pricing-proxy-cron
LAST DEPLOYED: Tue Aug 3 12:09:22 2021
NAMESPACE: dev
STATUS: deployed
REVISION: 1
TEST SUITE: None
Waiting for deployments to stabilize...
Cleaning up...
release "local-pricing-proxy-cron" uninstalled
could not fetch deployments: could not fetch deployments: deployments.apps is forbidden: User "REDACTED" cannot list resource "deployments" in API group "apps" at the cluster scope: requires one of ["container.deployments.list"] permission(s).
```

```shell
kubectl auth can-i list deployments.apps -n dev #proper permission at namespace level
yes

kubectl auth can-i list deployments.apps #not enough permission at cluster level
no - requires one of ["container.deployments.list"] permission(s).
```

Since the namespace is defined in the release object, I expect it to check the deployement in this namespace and not at cluster level

If a namespace is defined in kubeconfig, it works
If a namespace is provided in the skaffold command "skaffold dev -f .\skaffold.cron.yml **-n dev**", it also works

The issue seems to be occuring during the statusCheck phase, the namespaces property contains "" & "dev", hence making the check at cluster level for ""
