[PATCH widget-toolkit] api-viewer: fix handling of 'null' return schema

[Dominik Csapak]

when the return schema is 'null', there are no schema properties
to check, so don't try it it all.

This fixes an issue where rendering would stop with the error:
`can't access property "properties", schema is undefined`

Fixes: 7826b0a (api-viewer: support allOf and proper oneOf)
