Choosing a non existing project in the welcome screen will crash QtDS

When creating a new project and closing it. Then removing this project in the file browser won't update the welcome page Recent Projects list which as a result will screw the actual project which opens after clicking on an item in this list and if one project was removed clicking on the last item in the list will crash QtDS.
This is caused by the list not being in sync with the file system. Probably something like the Project view must be implemented which in sync with the file system. If an asset which was prior importer will be removed via the file browser it will directly be reflected in the Project view.
The Recent Projects list will only be updated after restarting QtDS or opening the File menu.
