Bug when adding/removing destinations in routing plugin

[Saikrishna Arcot <saiarcot895@…>]

What steps will reproduce the problem?

1. Enable the routing plugin, and add a routing layer.
2. Switch to the routing layer.
3. Add/remove a destination by clicking on a node

What is the expected result?
A destination flag pops up/is removed without error.

What happens instead?
An error box pops up, and the flag doesn't appear. However, after zooming in/out, the flag does appear and (when there are multiple flags), routing is displayed, so it seems the flag has been added, but the map isn't being repainted because of this bug.

Please provide any additional information below. Attach a screenshot if
possible.
