Fix introduced by NXP-28495 cache invalidates the "Empty document created" event handler

Solution introduced in NXP-28495 (HF22) caches the document creation response from the server. If there is any dynamic code in the "Empty document created" event handler, such as Fn.getNextId("case") title assignment, the empty document call to the server is skipped and the previous (cached) value is returned.

Unable to dynamically populate any value after the initial call. We use this for unique ID creation, date assignments to fields, etc. at time of creation.
