Added instructions for RecyclerAdapter cleanup & corrected method names

Somebody that wants to jump right in and use the `RecyclerAdapter`, might just skip through the `ListAdapter` example and forget to call `cleanup()` on it. Also, the method name seemed to be incorrect in the instructions but right in the code: instead of `release()` the correct method is `cleanup()` just like above.
