Fix error string for lookupAfterWrite (#208)

The following error string was the end result of an error in lookupAfterWrite:
  `set password configuration: update: lookup error lookup after write: failed record not found`

The error string with this change applied would be:
  `set password configuration: update: lookup after write: record not found`
