Fix timeout for no metadata run session

[Acuadros95]

Spin is not waiting if a session only haves timers, ending in a 100% CPU usage with code like this one: int32_publisher.

Also, we should run all sessions atleast once, to ensure a response to incoming data (From Hard liveliness check for example).
