I have a simple model where a Farm has_many Crops and Crop belongs_to Farm. If I  call `farm.crops.none?`, it appears to cache the wrong value for crops in the QueryCache and subsequent calls to farm.crops only list 1 crop, even if there are 5 associated crops.

For example:

```

3.0.0 :003 > farm = Farm.first
=> #<Farm _id: 609d35aefc70933c95aa9732, ...>
3.0.0 :004 > farm.crops.count
=> 5
3.0.0 :005 > farm.crops.none?
=> false
3.0.0 :006 > farm.crops
=>  [#<Crop _id: 60c01fd0fc7093b20bcdb452, ...>]   <= Notice only 1 crop in the array, should be 5
3.0.0 :007 > farm.crops.count
=> 5
3.0.0 :008 > farm.crops.to_a.count
=> 1

```
