Optimistic rendering on metadata queries

[pacyL2K19]

Bug Description

Similarly to #5278 > When you delete an object, the api takes long, the menu stills showing and if you mistakenly delete again, you get a “Error: ApolloError: Object does not exist” error.

Same when you want to deactivate an object, it takes a while → this doesn’t show an error, but we should prevent it from happening

Steps to reproduce

Expected behavior

• We should prevent to display the menu containing action buttons until the api call fullfils
• We should cut off the loading time on object deletion
• [suggestion]: add a confirmation modal before deleting the object, since this is a permanent action to prevent inadvertent deletions of object

@FelixMalfait feel free to update the issue, based on the suggestion above
