Since deserialized context value of Token model by getting through
AttributeSet#attributes is passed by reference, additional env values
passed to create_child_token method overwrite a context which a token
instance variable has. This cause unintentional env values propagation
like KUROKO2_PARALLEL_FORK_SIZE at outside of the fork task scope.
To avoid this, use the deep copy for context value instead.
