fix(async): slightly better support for nested coroutine contexts (#600)

* fix(async): only dispatch first failure in a.wait_all

* add InstallContext:run_concurrently

This is needed due to how multiple coroutine contexts are used in a hierchical
structure, and the async coroutine dispatcher loses this hierchical context
inside callback functions invoked via FFI (I… assume?).
