Title: allow builder's request_format to default to 'json' like engine

Handles extended templates whose format is nil to find
the right template and works similar to how engine
is already working.

Unfortunately, I couldn't find a good test to setup
to mimic what I'm seeing though it does fix a problem
I have in my project.
