no config debug: Fix error when multiple vscode windows are open

Should fix #916, but getting this installed locally seemed sufficiently complicated that I gave up.
Fix is:
1. Only watch a specific endpoint file
2. Make sure this endpoint file is unique (I imagine the workspace file path can be non unique across vscode windows)
