Changing old boards requires a mailinglist
One-sentence description
Changing old boards requires a mailinglist
Current behaviour / Reproducing the bug
I tried to change the board member ship of Joris Reichert and Lore Veugen and Simon Brugman (because they left a board and we can now edit this). But when changing this, I got an error message saying the board needs to have an mailinglist. This is undesired since old boards have their own automatically created mailinglist.
Expected behaviour
Not have this error message
