Status wrong when allowCrossNamespaceImport is set to false and grafana isntance is deployed in another namespace

[NissesSenap]

Describe the bug
The status field will show as matching instances even if you deploy a grafana instance in one namespace and your dashboards in another one, even if grafanadashboards.spec.allowCrossNamespaceImport isn't set.

This makes it really easy to think that your dashboard should be synced, but since the operator won't sync crossnamespace grafanadashboards it's makes it really hard to understand why they don't show up in your grafana instance.

Version
v5.2.0

To Reproduce

• Follow the instructions in CONTRIBUTING.md how to setup your own Local development using make run.
• run make run
• Create a new namespace called test
• Create a dashboard in test

Expected behavior
Since I haven't set grafanadashboards.spec.allowCrossNamespaceImport in my dashboard i should get

➜ k get grafanadashboards.grafana.integreatly.org -n test
NAME                                  NO MATCHING INSTANCES   LAST RESYNC   AGE
custom folder                              true                                      2m36s         2m36s

Instead, I get

➜ k get grafanadashboards.grafana.integreatly.org -n test
NAME                                  NO MATCHING INSTANCES   LAST RESYNC   AGE
custom-folder                                                                          2m36s         2m36s

Which means there is a sync.
