Fix #36639, textures not reloaded after fixing paths.
The BKE_bpath_traverse_id method updates path variables of image data blocks, but did not cause the image to be reloaded (or rather, tagged so it gets reloaded on next use). This requires also updating
all the ImageUser "ok" tags, which happens in some odd places in other cases where reload happens (e.g. the reload operator and the image path button handler function in image template).
