Intersections aren't removed when roads get deleted

Description
Often when I create a road network, and them delete certain roads, the spines remain in place and make it impossible to continue to make a road network.

How to Reproduce
Create a road network, delete certain roads, try to re-add roads.

Expected behavior
The splines should be removed as well.
