fix: show trash breadcrumb with one space

[fredrikblau]

Description

The app bar hid breadcrumbs on the trash route when the personal space was the only available space. This left the trash view without its “Deleted files” breadcrumb.

The special-case suppression is removed, and a regression test covers the single-space trash route.

Thanks 👍

There is a little deviation to the expected outcome described in the initial issue, the Breadcrumb is showing Deleted files > Personal which is totally fine for me
