• Extension version: 2019.8.30787
• OS and version: ArchLinux, Latest
• Python version: Python 3.6

Expected behaviour

Does not show warnings

Actual behaviour

Shows warnings, even if the checked code doesn't exist (anymore)

Steps to reproduce:

Sadly I don't know how to reproduce this. I got this also in another file. In the other file it could be resolved, by deleting the file and recreating it + posting the old code in there. This isn't possible here.
