UI glitches when downloading single package on a long list of updates

[genodeftest]

This is not a crash, thus there is no crash report.

Expected behavior
Only show download indicator for a single package.

Actual behavior
Yalp shows the download indication on several packages, about one per screen.

Steps to reproduce

1. Open yalp store
2. Show updates. This issue only happens if there are more updates than what fits the screen. In my case that's about 7 packages.
3. Press the download button for a single app
4. Scroll down at least a whole screen

Your setup
Yalp version: 0.45-legacy (from f-droid store)
Android: 9, security patch level 2019-01-01, mostly stock (Nokia).
Device: Nokia 5 (TA-1053)

Additional information
This issue may be related to #523 as I sometimes see signature mismatches when the issue happens. I will report back when running in this combination of issues.

This is a reopened clone of #584 because the "stale" bot ran haywire on it.

I was told by an android developer that this issue happens because the number of UI items is limited and instead of creating a UI item for each package, yalp (wisely) reuses the list elements replacing both strings and icons. It does however seem to fail to remove/set the "is downloading" status.
