Fix potential get_wait hang if queue only receives a list in `put_w… (#298)

* Fix potential `get_wait` hang if queue only receives a list in `put_wait`

`get_wait` would never have its waiter woken up if a list were to be passed in an atomic `put_wait` with no subsequent calls of another type.

* Move fix to `put_wait` instead of `put`
