Serialization of trust path results in extra nested trust path on every serialize

Description

When a PublicKeyCredentialSource is serialized the trust path gets nested into an additional layer every time serialization occurs.

How to reproduce

1. Have a PublicKeyCredentialSource with trust path with a certificate
2. Serialize it
3. Observe that after every serialize, the trustPath has an extra level of nesting

"trustPath": {"x5c": {"x5c": {"x5c": {"x5c": ["-----BEGIN CERTIFICATE-----

This doesn't stop anything from working, but we ended up with keys saved with so many nesting levels that we reached the max nesting level in the database.
