Bug 400542

SUMMARY
On Krita's new welcome screen there is a Recent Documents list, pressing Clear there removes all listed items. However, it displays items incorrectly in some occasions.

1) After pressing Clear, the current items stay visible until Krita is restarted.

2) When the list is empty, drag one document into Krita and then close it (do not close Krita), Recent Documents list now displays 2 duplicated items of that document. Restart Krita and the duplicated items are gone.

3) When the list has only one item A, drag another document B into Krita and then close it (do not close Krita), Recent Documents list now displays A and B alternatively until they fill up the list. Restart Krita and the duplicated items are gone.

Tested on Manjaro KDE 18.0, krita-4.2.0-pre-alpha-4b9572f-x86_64.appimage
