Problem with party dates: some MPs belong to a 19th party AFTER the party has ceased to exist

[fredrik1984]

We have found out that some MPs in the bio books belong to a party after the supposed existence of that party.

A good example of this is the party called "centern" (AK/second chamber, Q10444846) in the bio books, which is stated to have existed between 1873 and 1882 (see the so-called party tree in the intro of the bio books). We have found several MPs that are stated to belong to this party but after 1882. For example: https://www.wikidata.org/wiki/Q5568434 and https://www.wikidata.org/wiki/Q5795740. I suspect that these MPs belong to the seemingly similar party "AK:s Center" (1889–1894). What do you say @Lottabrorsson?

We should go through MPs that belong to these 19th century parties (or at least a sample of them) and check their party belonging. For example, make sure that no MPs are member of a party outside that party's start/end year.

This might be something for @Lottabrorsson and Mattias to dig into later on!

This issue relates to #375 and #201 and #191

This would also be a good data integrity test in the long run.
