Some translations appear when the language is set by the OS but do not appear when the language is set within the app

Expected behavior

Translations that work when the language is set at the OS level should also work when the language is set within the app.

Actual behavior

Some translations only show up when the language is set at the OS-level.

Steps to reproduce the behavior

1. Create a post with a media block that has a failed upload (airplane mode is handy for this). From the posts lists, tapping the retry button on the post should cause the "1 post with 1 file not uploaded" error message.
2. Fresh install of the app or install of the app that has never had a language set from within the app. It is important that the language never have been set from within the app on this install because once the language is set within the app it will override any OS language settings until the app's data is wiped.
3. Set the OS language (Settings -> System -> Languages & Input -> Languages) to "Deutsch (Deutschland)".
4. Within WPAndroid, observe that the "1 file not uploaded" notification is properly translated to German.
5. Change the OS system language back to English
6. Within WPAndroid (Me -> App Settings -> Interface Language), change the language to "German (Deutsch)"
7. Observe that the "1 file not uploaded" notification is not translated to German.

Start by reproducing the failed-upload notification using the listed OS-language and in-app-language steps on Android. Trace how the app selects translations for the notification in each case; done means the same German translation appears whether German is selected by the OS or within WPAndroid.
