landscape: confusing empty states in software search

[dnbrwstr]

If you click the empty search input twice while searching for software, or if you enter a query then delete it, we display search suggestions with outdated content.

The "Groups" app link shown above opens the old version of groups, and the developer (~dister-dozzod-dozzod) only distributes the old groups, and a version of terminal (probably also old).
