Avoid falling back to MOD label when rendering oneOf/anyOf and title not defined (#455)

* Add preprocessing step to inject title attribute to component schema if none exists

* Add CloudAccounts for testing

* Remove CloudAccounts from demo

* Remove title attribute from components schemas

* Revert back to petstore
