Ltex not starting automatically for python files

[mgorfer]

Describe the bug
Ltex is only starting the analysis of a python file after opening a tex file first.

Steps to reproduce
Steps to reproduce the behavior:

1. Open a .py file
2. Ltex does not start running
3. Open a .tex file
4. Ltex starts and now also works for analyzing comments in the .py file.

Expected behavior
Ltex starts up for every file type defined in ltex.enabled in the settings.json

LTeX configuration
Please paste all configuration settings starting with ltex. from your settings.json. You can help us by temporarily removing some irrelevant settings from your settings.json and see if the bug still occurs.

Also having this issue with C files instead of python.
Same behavior : doesn't start on C files before opening a tex file. But works great after opening a tex file.
