Do not rely on initials for people detection when a full given name is provided

[cnrdh]

Here, "Juliana A." is mis-connected to as "Jesper A.": https://akvaplan.no/en/doi/10.1007/s10584-021-03041-z

[cnrdh]

Another example: https://akvaplan.no/no/folk/id/xwa/Wang/Xinxin

Here the listed publication is not by Xinxin, but by by Xiaoyu
Double problem: https://akvaplan.no/no/folk/id/xwa/Wang/Xiaoyu should give 404

[cnrdh]

Currently, the URL https://akvaplan.no/no/folk/id/xwa/Wang/Xiaoyu looks up Xinxin Wang since they share family name and first initial.

The trouble comes from using names from publications to link to a person page.
The current logic handles linking from publications that only use family name and initials to identify people, but should not be used when a full given name is provided.
