Remove env() getter from JavaRef<>

    Due to threadsafety ambiguity, it's not generally safe to call env()
    on a random Ref you've been passed, so this removes the temptation.
    The useful LocalRef optimizations are retained though, just in that
    sub-class.

(upstreaming CL, cherrypicked cleanly)
