Simplified OCP validation
Now only rule. User can't validate himself.
But validations can still be done in commitment/box or process levels.
Ex. here: https://ocp.freedomcoop.eu/work/process-logging/171/
now since there are 3 validations from the 3 participants, their work will be correctly validated since each one got 2 validations from the other 2 participants. Before all validations were getting canceled which was bringing to confusion.
