Fix authentication with (older) identities that have devices without a (valid) credential id.

[sea-snake]

Fix authentication when (older) identities have devices without a (valid) credential id.

Changes

• Reimplement old behavior from previous release where devices without a (valid) credential id are filtered out.
• Improve guarantees during build time by moving credential id checks into convertToCredentialData method itself.

Added Tests

• Check if devices are ignored with missing credential id
• Check if devices are ignored with invalid credential id

Already approving, but please check my comment about renaming instead of creating another function.
