Fix T49826: NEW-DEPSGRAPH - Texture is not updated after changing its space color

Browse Source 
The issue was caused by image ID nodes not being in the depsgraph.

Now, tricky part: we only add nodes but do not add relations yet. Reasoning:

- It's currently important to only call editor's ID update callback to solve
  the issue, without need to flush changes somewhere deeper.

- Adding relations might cause some unwanted updates, so will leave that for
  a later investigation.
