Confirmed on my end. Just created a farm myself, and the villager won't harvest anything.
Edit: Out of curiosity, did you use a specifier on the spawn egg to ensure it was a farmer? When I use a plain spawn egg, it appears to be working, but if I use a spawn egg to ensure it's a farmer, it does nothing.
Strangely, reloading the chunks appears to also work, but after summoning, he wouldn't do anything until the chunks are completely unloaded and then reloaded.
