CURA-6015
ListModels should not modify items directly. All ListModels should use
setItems() and the insertions/removals/modifications will be done in
setItems() itself.
Cast every sorting key to uppercase before doing this. Don't cast to lowercase or there will be problems with characters that don't have lowercase and with Turkish dotted i vs. undotted i.
Fixes#3460.
