Fixed
- Using nonce credentials now works as expected for `transformations.[create, update]`. Previously, the attempt to create
a session would always fail, leading to nonce credentials never being used (full credentials were passed to- and
stored in the transformations backend service).
- Additionally, the automatic creation of a session no longer fails silently when an `CogniteAuthError` is encountered
(which happens when the credentials are invalid).
- While processing source- and destination credentials in `client.transformations.[create, update]`, an `AttributeError`
can no longer be raised (by not specifying project).
Added
- `TransformationList` now correctly inherits the two (missing) helper methods `as_ids()` and `as_external_ids()`.
