Select multiple allow methods for rpc shows wrong error

[jaapio]

When you edit an RPC service the UI allows me to select multiple allowed methods. But it seems to be imposible to process this. The backend will show the error:
"controller_class: The Controller Class must be a valid, fully qualified, PHP class name" which is a strange error since I didn't change the controller class at all
