Remove emoji annotations code for unused languages from final build

Resolves #1361 (closed)

Changes

• Remove emoji annotations code for unused languages from final build

Test Plan

In dev and prod build:

• Verify you can load emoji annotations for other languages and search for emojis in them
• Verify that selecting a language without corresponding emoji annotations (e.g. eo) should not crash the app (there should be a log in the console though)
