Fix T43831: Image Editor: Render info not displayed

Issue was caused by b62c2a9 and root of it goes to the fact that text
info is stored in the "main" scene, not the currently rendering one.

This is a bit annoying but making it so text and result are coming
from the same scene is a bit dangerous to do now. Will re-visit this
change after the release and see if it might be done in a more clear
fashion.
