fix #2355: "move workspace to output up" crashes

when using 2 display, if scaling is different
`container_update_textures_recursive` is called when moving workspace on
different display.
We need to call `container_update_title_textures` only for container of type
"CONTAINER" or "VIEW" in order to be consistent with the assert in
`update_title_texture`.
