remove methods arg to requestVerification(DM)

as it's easy to have this argument be out of sync from all
the places this is called from the js-sdk. There is also little point,
as you can already specify the methods a consumer of the js-sdk
wants to provide through the verificationMethods option when creating
the client object.
