`kctrl`: Incorrect error message when package not present

**What steps did you take:**
I tried installing a package for which the version didn't exist:
```bash
kctrl package install -i foo -p foo.myorg.com -v 1.0.0 -n test-ns --values-file ~/Workspace/test-yaml/kc/kc-package-test/itr2/kc-package-values.yml
Target cluster 'https://192.168.64.23:8443' (nodes: minikube)

8:39:53PM: Creating service account 'foo-test-ns-sa'
8:39:53PM: Creating cluster admin role 'foo-test-ns-cluster-role'
8:39:53PM: Creating cluster role binding 'foo-test-ns-cluster-rolebinding'
8:39:53PM: Creating secret 'foo-test-ns-values'
8:39:53PM: Creating overlay secrets
8:39:53PM: Creating package install resource
8:39:53PM: Waiting for PackageInstall reconciliation for 'foo'

kctrl: Error: packageinstall/foo (packaging.carvel.dev/v1alpha1) namespace: test-ns:
Reconciling: . Reconcile failed:
Package foo.myorg.com not found
```
^This works as expected, but when I try running the same command again, I got a different error:
```bash
kctrl package install -i foo -p foo.myorg.com -v 1.0.0 -n test-ns --values-file ~/Workspace/test-yaml/kc/kc-package-test/itr2/kc-package-values.yml
Target cluster 'https://192.168.64.23:8443' (nodes: minikube)

8:39:55PM: Pausing reconciliation for package installation 'foo' in namespace 'test-ns'

kctrl: Error: Waiting for app 'foo' in namespace 'test-ns' to be paused: apps.kappctrl.k14s.io "foo" not found
```

**What happened:**
kctrl tried to update the existing package install, and while doing so, it first tried to pause the app cr which doesn't exists yet as the package itself was not found.

**What did you expect:**
I expected the correct error message to pop up again.
