When farmer villagers work, the subtitles read "composter filled" and also "farmer works." This is kind of silly. 

Steps to reproduce:

1. Enable subtitles
2. Spawn a villager and provide it with a composter so it becomes a farmer
3. Without providing it with anything to fill a composter with, wait for it to work at the composter
4. Observe the subtitles and the fact that the composter is not, in fact, filled

Expected behavior:

The subtitles would only read "farmer works"

Observed behavior:

The subtitles display both "composter filled" and "farmer works"
