Fix broken test cases in DeflaterTest & InflaterTest

We explicitly disallow setLevel or setStrategy after
setInput. (It's clearly documented in the method docs).
Presumably, this is to prevent users from shooting
themselves in the foot & causing issues by changing
the strategy / level after we've started deflating.
