test/api: race-free api.metadata access

Browse source 
Access metadata.api only after `api` has exited the context and
thus the event loop has stopped and all incoming messages, like
the one setting the metadata, have been processed.
See commit 803433fb62 for a lecture
about the internals and all the details involved.
