Partial extractions have some unexpected results

Describe the bug

Running lingui extract on certain files (using either husky or running manually) is giving some unexpected results.

1. it looks like obsolete translations aren’t being marked as obsolete (#~msgid "")
2. unrelated file path comments are being removed in other unrelated translations

Regarding the second point, I haven’t seen this happening in our example repo used below, but it might just be the fact that there are very few strings involved. In our real project, we have lots of entries which are grouped together by msgid and have file location comments above.

~I’ll try to make a reproducible example of this when I can.~ EDIT: There is now a reproducible example in comments.

To Reproduce From our example project: We changed a text from {t`Version ${version}`} to {t`App version ${version}`}.

Running lingui extract src/login/view/Login.tsx resulted in this: https://github.com/kerlends/lingui-extract-bug/commit/4cec61a2b3698fb13819ca935dbc1f2646c36c05

Running lingui extract resulted in this: https://github.com/kerlends/lingui-extract-bug/commit/ffb6413d5eb2fd15836e1856ac95b4ddccb6c071

Try yourself:

git clone https://github.com/kerlends/lingui-extract-bug.git
git checkout text-changed-without-extracting

lingui extract src/login/view/Login.tsx
git diff

git checkout -- .
lingui extract
git diff

Expected behavior Partial extraction should mark the previous message obsolete if not used elsewhere. Partial extraction should not remove comments from unrelated translations

• jsLingui version 3.12.1
• Babel version @babel/core@7.15.5

We have a bot that marks issues as wontfix after no activity, but indeed this is a bug and shoudn’t be closed. I’ll try to get some time for Lingui asap.
