[MC-151185] Game crash after breaking villager point of interest

The bug

So, I was playing in my own world in 1.14.1 pre-release 1 today. And i was testing some villager mechanics, and i placed a bed, but when i tried to break it the game immediately crashed. Please fix this bug.

Edit : I tried the bug again but it didn't crash this time even though i tried it a lot, at the same conditions.
