Home screen displayed when all files are in a project are closed

When the last open file of a project is closed, QDS returns to the home screen even though the project is still open. This is very confusing because it gives the impression that the project itself has been closed.

Steps

• Open any example project
• Close all files (x button next to file name / Ctrl + Shift + W / File --> Close All)
• The home screen is displayed

Suggested behavior - keep the empty project displayed. It is possible to return to this state by pressing Ctrl + 2, but this is an unnecessary operation for the user.
