Subject: [PATCH] Fix example generation when missing models (#11805)

For some buggy configurations, a warning is emitted indicating that for
a given request body the corresponding CodegenModel could not be found.
When this happens, some generators produce NPEs when writing out example
code. This change avoids the NPEs by providing a stub value instead.
