fix(web/converse): Bare minimum changes to build in 2021 r/2443

This project depends on Tokio, via actix, and both of those are bad
ideas. This wasn't as clear 3 years ago as it is now, but to
demonstrate it the project has amassed issues which required at least
this minimum of changes to be buildable in 2021 (using a modern
rustc).

Yes, this adds dozens of new dependencies again (because of a
top-level update) but don't worry: They will be gone when I'm done
here.
