REST API: Make template handling resilient against plugins setting the global post. 

Plugins shouldn't be setting the global post object during a REST API request, but if they did this could cause unexpected errors when creating a post with a template.

Props Kipperlenny, TimothyBlynJacobs.
Fixes #49695.
