Update of resource at close of app does not work

[jakob-sikken]

The Twente apps are auto saving. They use two save strategies: save after changes and save unsaved changed just before closing the app.
The saving of unsaved changed just before closing the app is not handled by the graasp-desktop app. The update command is send away by the Twente app.
This can easily be tested by changing anything in on of the Twente apps and within 1 second go to another phase. When you go back to the phase with the Twente app, you will see the last change was not saved.
