merchant view: remove 'note'

[escapedcat]

Note can go as it's for mappers, not users.

1. i.e. see: https://btcmap.org/merchant/node:341291582
2. see note "fehlt in Adressenliste Stadt München, Hausnummernschild (blau) vorhanden #Adressenabgleich"
3. remove the code and the related unused code after

Maybe also check for further unwanted occurrences
