fix: remove returned Futures from switch.start (#662)
* fix: remove returned Futures from switch.start

The proc `start` returned a seq of futures that was mean to be awaited by the caller. However, the start proc itself awaited each Future before returning it, so the ceremony requiring the caller to await the Future, and returning the Futures themselves was just used to handle errors. But we'll give a better way to handle errors in a future revision

Remove `switch.start` return type (implicit `Future[void]`)

Update tutorials and examples to reflect the change.

* Raise error during failed transport

Replaces logging of error, and adds comment that it should be replaced with a callback in a future PR.

fix connection event order when connection dies early (#351)
if the connection is already closed (because the remote closes during
identfiy for example), an exception would be raised which would leave
the connection in limbo, beacuse it would not go through the rest of
internalConnect.

Also, if the connection is already closed, the disconnect event would be
scheduled before the connect event :/
