Texture Paint: sync adding a new texture slot to the Image Editor

When changing the texture paint slot index or activating a Texture Node, the texture displayed in the Image Editor changes accordingly.
This patch syncs the Image Editor when a new texture paint slot was added, which currently is not the case.

Also deduplicates some code.
