A number of methods of ipykernel can optinally return `awaitable[T]` instead of just `T`, this is the case for `do_complete`. I think it's a mistake ; see ipython/ipykernel#1295 ; in particular because it's easy to forget / hard to properly type-check, and I'd like to make it mandatory in the long term to have await. Spyder seem to not handle the case where do_completer return an awaitable (or more partiularly is `do_complete` is a coroutine function. This tries to handle it – and as of course `do_completer` _can_ be async, all caller _must_ be async. So I try to do all the required updates. Note: I also add explict imports in some test, to get better error message in case those deps are not installed.
