region_statistic_fix

What does this MR do?

fixes some small things on region statistic page :

• pickup list includes now stores in subdistricts
• added year to pickuplist
• generalist : "divers" and "not selected" seperated - it is to confusing to have two entries with same description and it doesn't make sense to mix them,
• fix seed script returning 1
• fix http link on statistic page always return to home district when looking at statistic of foreign district.
• gender seed generation now includes divers and "not selected"

How confident are you it won't break things if deployed?
