Revisions: only create autosave when content changed.

Browse Source 
In the autosave REST API endpoint, avoid excessive database writes when an autosave is sent with content that is unchanged from the saved post. 

Before this fix, clicking "preview" in the editor (which uses the autosave feature) multiple times would cause an identical autosave entry to be deleted and re-created repeatedly.

Fixes #49532.
