fixed check to allow temporary and misassigned UPNs
<FormerUPN> (N00002) where present should be in the correct format, as specified in the data table
Note, there are multiple types of former UPN, there are Temporary UPNs which end in a letter, and those where a child is assigned a UPN but then another is identified for them having been used previously. If this was only a check for temporary UPNs, it would check that the last character was a letter.
