In this PR

Fixes HAAS-440 Turns out I already implemented the ability to set contact persons per team in a previous PR 😅

So this PR contains:

• A test for setting contact persons via CSV

• A test for overriding a template via CSV

  

• Extra info on what kind of values could be entered in specific columns of the csv
