    Fix example fiber scheduler reg. writable events · 9c058270

    There were two issues:

1. When an IO object is waiting for writablility only (as in test_tcp_accept) the selected hash is empty.
   Therefore selected[fiber] returns nil but needs to default to 0 in order to be or'ed with IO::WRITABLE.

2. When an IO object is waiting for read- or writability (as in test_tcp_connect), but only one of these
   two events arrive, the Fiber and IO object need to be removed from the other `@readable` or `@writable` list.
