de.tutao.tutanota very close to reproducible builds

Bug in mobile app

Describe the bug

There looks to be unsorted generated output in assets/tutanota/sw.js which is the only thing breaking reproducible builds for the APKs. It looks like these items in particular do not have a fixed order:

• invoice-DyIaiday.js.map
• native-common-DuMw-wf5.js.map
• translation-en-D8ZBhL8N.js

To Reproduce

1. Run the build twice
2. Use diffoscope to compare the resulting APKs
3. See the diff: https://verification.f-droid.org/de.tutao.tutanota_396418.apk.diffoscope.html

Expected behavior

Sorted output so the build is reproducible each time it is run. It should be a simple fix: just sort the file names before before adding them to assets/tutanota/sw.js.

sw.js should not be included in Android app anyway 🤔
