Fix parsing problem when adding or removeing accounts/users to an existing reservation

preserve a reservation's start_time_prev value

first association record and just use NO_VAL to match the account's 
association record

 is either COMPLETED or COMPLETING (which can hang for some time)

Set a job's resv_ptr only on slurmctld restart or reconfig, 
  then use xassert() rather than redundant calls to find a 
  reservation by name.

Fix logic for testing if reservations overlap considering DAILY reservation flag

remove redundant test "-h" and "--help" should be equivalent

append (Path), making it more consistent with the other values

  a node count at the same time.
