Django debug config selection: Manually entering the path does not work

[aeschli]

Testing #279

• create a new launch config: Python Debugger > Django
• In the dialog do not select a suggested option, but enter ${workspaceFolder}/moooo.py. That location does not exist (yet).
• Press Enter

The created launch config references "program": "${workspaceFolder}/manage.py", not moooo.py
