[book] duplicate entries

[tuurma]

part of #285

Σελαμανης 9 and 11 are duplicates, listed under slightly different headings. However, when I checked in the system, there is in fact only a single entry. So, somehow that entry is being output twice. This obviously is a concern if it is in some way a systematic issue

(...) single person outputting 3 times (Σέργις 102, 107, 109: P108945f0-5193-4546-99df-389dbb738899; 103, 108, 111: P495d2786-5b38-454a-9235-9b114e0e5350). In the former case, the person also has an alternative place of origin, which should appear in the final bracket but does not. In the latter case, I think it may have to do with people from places where the "Group under" tool has been applied

(...) Σέργις I have noted several more false duplicates (116 & 118; 128 & 130) where the problem seems to be caused by both being entered as territ.? in the original forms.

All seem to be connected with uncertainty (?) and (territ.) markers present, sometimes in combination
