Error message incorrect when deleting device that is not present #20

When initializing CB with a different primary user/device an error is returned if the previous device does not exist.

ERRO[2022-05-02T13:24:12-04:00] DeviceAPI.UnRegisterDevice(): deleteDevice mutation returned an error: Message: Given device was not found, Locations: [{Line:1 Column:26}]

It appears the error returned from GraphQL is parsed incorrectly
