bug(web): Inform user when deleted topology is still used

This change fixes #135 which showed that trying to delete a topology
used by a scenario would result in nothing happening in the UI and a 500
error being returned by the server. We check whether a scenario still
references the topology and show an error to the user if that happens.

Fixes #135
