fixes #24

Merge pull request 'Get device_id from body instead of auth data' (#27) from gnieto/conduit:fix/create-device into master

Device_id was retrieved from the auth data instead of login's body and
this was causing that a new device was created on every login.

This is (I guess) provoking that some sytests are failing (for example,
"POST /login returns the same device_id as that in the request").
