We're often grabbing the metadata of a specific thread to then be able
to perform other operations, but we never need the actual responses or
comments of a thread unless we're displaying it in the normal forum
view.

This change sets a default of with_responses=False, which instructs the
comment service to not send back the responses/comments for the given
thread.  We only ask for responses in the case of rendering a single
thread or inline discussion.
