Don't provide props via navigating

[raimund-schluessler]

Passing params that are not defined on the path will break with vue-router 4.1.4, since it's an anti-pattern. See https://github.com/vuejs/router/blob/main/packages/router/CHANGELOG.md#important-note.

So we don't do this anymore and instead open the tab via an emitted event after the AppSidebar was mounted.
