Remove no longer necessary msg parameter from try_with_* functions
With the move to using anyhow's Error type and adding contextual information at the point where we bubble up errors, we no longer require the 'msg' argument that is passed to the try_with_pin_* and authenticate functions. To that end, this change removes this parameter, concluding the switch to using anyhow.
