Steps to reproduce

1. Save an email to nextcloud (in my case from thunderbird) with file-extension .eml
2. Open the current nextcloud Android App (V3.10.0)
3. Open the .eml file

Expected behaviour

• The popup with apps to open the file with contains email programs (such as GMail)

Actual behaviour

• Only text viewers and other apps are shown, but no email app
• When opening

tools/unix/generate_localizations.sh is the starting point.
