This commit fixes that error, and adds support for IdentityLink.

* TripleLift: Sending schain (#1)

* Sending schain

* null -> undefined

* Hardcode sync endpoint protocol

* Switch to EB2 sync endpoint

* Add support for image based user syncing

* Rename endpoint variable

* Add assertion

* Add CCPA query param

* Simplify check for usPrivacy argument
