fix token API not returning IDs anymore

[nicolai86]

Scaleway recently overhauled their token API - now there are a couple of changes:

• there are two new attributes: access_key and secret_key.
• the ID is no longer present in the response payload. It seems it has been deprecated in favor of access_key
• Fetching keys can be done by the AccessKey instead of the ID, too.

To make this a non-breaking change the SDK now sets the ID when reading with a specific ID.

Note that due to the API changes on Scaleway's side the tests are broken without this change.

All tests are green (together with #87)

otherwise LGTM 👍

[tombuildsstuff]

we probably want to set Sensitive: true here?
