Cancel waiting tasks on resolution error (#753)

Browse source 
## Summary

I don't understand why this works (because I don't understand why it's
erroring) but it does. See:
https://github.com/astral-sh/puffin/pull/746#issuecomment-1875722454.

## Test Plan

```
cargo run --bin puffin pip-install requires-transitive-incompatible-with-transitive-8329cfc0 --extra-index-url https://test.pypi.org/simple -n
```
