<modify_order action="reset"/> doesn't work in nested job chains

If you call <modify_order action="reset" order="" job_chain=""/> where the master job chain is used in the job_chain attribute then nothing happens.
If you call <modify_order action="reset" order="" job_chain=""/> where the nested job chain is used in the job_chain attribute then Job Scheduler tries to set the order to its initial state, but this state is not a state of the nested job chain, so that an error occurres:
SCHEDULER-149 There is no job in job chain "..." for the state "master_initial_state"
where "master_initial_state" is the state of the master job chain
