Simplify how flatpak addons are displayed.

We normally queue up addon install/remove tasks with the flatpak
system. This provides us with freed/used disk space values for
each addon.

Unfortunately it turns out some flatpak apps have so many available
addons that it crashes flatpak when you select the app (too many
open files).

Instead of creating install tasks for every addon, just list them
without disk space info (it's usually not significant anyhow).
