Message:

Revisions: return existing autosave after saving with unchanged data.

Correctly return the existing autosave when an unchanged autosave is saved, instead of returning an error.

Fix regressions after r55154 where an error and not the original autosave was returned when saving with unchanged data (for example, clicking the preview button repeatedly). Returning the autosave (ID) is the expected behavior for the endpoint.

Follow up to [55154]

Props Mamaduka, jeroenrotty, mrfoxtalbot.
Fixes #58739.
