top-level remote libraries in 5.1.0

[kerneljake]

After restarting Lyrion 9.0.0-1719573325 to upgrade to Material 5.1.0, I did see Remote Libraries move to Apps, however there is a residual cloud icon remaining at the topmost level.

This icon is clickable, and I see a question mark and "2 items" even though there is only one item in the list. (The issue of having a 2-vs-1 mismatch has always been there, so that's not a recent development.)

Seen on Firefox 115.13.0esr on macOS 10.13.6 despite doing shift-refresh in the browser.
