Update notification doesn't include package name and version [Bug]

[spodermenpls]

Sailfish OS VERSION: 4.6.0.13 and earlier

HARDWARE: Sony Xperia XA2

SailfishOS:Chum GUI application VERSION: 0.6.8-1 and earlier

BUG DESCRIPTION

According to the locale string %1 %2 updated, %1 is supposed to act as a placeholder for the package name and %2 as a placeholder for the package version, that get displayed in a notification popup after a successful package update. However, package name and version never get displayed on my end, and have never done so (at least to my recollection) in the past either, it only displays "updated", or in my German case "aktualisiert" (which was the original thing that made me pay attention, since if indeed intended as a single word, it should be spelled with a capital "A" in that scenario). The notifications after Install or Remove operations however do include package name and version, as intended.

STEPS TO REPRODUCE

If there's at least one update for a package available (unfortunately not that easy to re-create on demand..), execute it from the pulley menu and observe the notification pop-up banner after it is done.

Thank you very much @spodermenpls for this excellent bug report. I will take a closer look at the corresponding code, when I find some time for SailfishOS-related things (but not the next couple of days, unfortunately).
