Fix RuntimeError

[Starkteetje]

We fail sometimes like here with RuntimeError: Timeout context manager should be used inside a task, which this PR fixes.

Description

Using the default initialization of the event loop (i.e. not doing it ourselves) seems to fix the problem (locally ran into RuntimeErrors 5/20 complexity integration tests before and 0/20 after fix)
