[FIX] web: reference field calls name_create

An older commit (50bf8309) had refactor part of the basic field _applyX2ManyOperations.
During this refactor, the reference field was forgotten to be included
in a condition that made the field no longer do the quick create behavior.
The name_create function in the backend was no longer called.

Adds a test for the reference field checking the call to the name_create
function and fixes the problem.
