kmsrecorderendpoint: Do not wait for EOS when no sources have been linked

in internal pipeline, so processes waiting for the singal completion never
were notified if not media flowed in the pipeline. This patch does not wait
for EOS in such cases throwing the proper signal without causing deadlocks
