Can you pass a FakePlayer to canSilkHarvest instead of null? This caused josephcsible/Oreberries#10 to occur. I worked around it via josephcsible/Oreberries@a842ed4, but I don't think I should have to do that.

Thank you for your report.

This is my mistake because canSilkHarvest doesn't have a parameter annotated @Nullable.
