Hi There, I'm wondering which of the two create_user calls are authoritative: 1. [authentifiation/api_call.rb](https://github.com/figo-connect/ruby-figo/blob/92e6df22ea04edd9ee32b2f0038686fb8537bf15/lib/authentification/api_call.rb#L61) 2. [user/api_call.rb](https://github.com/figo-connect/ruby-figo/blob/92e6df22ea04edd9ee32b2f0038686fb8537bf15/lib/user/api_call.rb#L38) Since their signature differ slightly, they are not compatiable. Cheers!
