conf: Expose iothreadids when delete non sequential iothreadids

Browse Source 
Since 'autofill'd iothreadid entries are not written during XML format
processing, it is possible that if an iothreadid in the middle of an
autofilled list would then change it's id on a subsequent restart.

Thus during the iothreadid deletion, if we determine the delete is not
the "last" thread, then clear the autofill bit for all iothreadid's
following the one being deleted (either the first or one in the middle).
This way, iothreadid's will be printed/saved.
