node not receiving inject once message

[birosz]

inject node configured in "inject once" mode but message is not received by the cronplus node.
usecase: i want to stop all predefined schedule timers in a cronplus node after boot by injecting once the stop command for every timer i have.
the json syntax is ok because it stops manually whenever i press the inject node, also i can catch it with a debug node after boot, but it will not work in inject once after boot even with a 10 second delay.
