Remove non-functional support of unique_ptr in produce_helpers.

[wmtan]

A very recent PR was added that included the addition of a template to produce_helpers in an attempt to support the use of unique_ptr in this context. This addition was not sufficient to support unique_ptr here, and may mislead users to believe that it is supported. As adding support for unique_ptr in produce_helpers is non-trivial, we just back this out for now so that users will not be mislead.
