When launching the plugin on an existing project, I cannot use it. IndicatorCancellationException

[adietish]

Steps:

1. ASSERT: use a project that is already indexed.
2. ASSERT: have RH Sandbox as current cluster
3. EXEC: launch the plugin

Result:
The resource tree shows an error and thus most actions are not available in the context menus:

ps. I am still not fully sure how to/not to reproduce it. It happens always to me.

Workaround for me: I touch ~/.kube/config which causes the resource tree to be refreshed and display the cluster, current namespace etc.
