@tzulitai, @GJL is correct, `Environment` is not
`Closeable`/`AutoCloseable`. Also I was afraid that someone might be reusing
some external environment, but I think that's not the case.
Using `environmentIsInternal` flag would require some casting, that's why I
have chosen `Optional`.
+1 for `internalEnvironment.ifPresent(MockEnvironment::close);`
