[SerializeReference] Editor crashes on Transfer<JSONRead> when calling JsonUtility.FromJson

Serialization

-

How to reproduce:
1. Open the attached project "case_1198073.zip"
2. Load the "SampleScene"
3. Enter Play mode
-- Observe the crash

Reproducible with: 2019.3.0b10, 2020.1.14f1
Could not test with 2017.4.35f1 and 2018.4.13f1 due to "The type or namespace name `SerializeReference' could not be found", 2019.2.13f1 and 2019.3.0a1 due to "SerializeReference inaccessible due to its protection level"

The crashes the editor when creating or overwriting an object from its JSON serialized representation

The crash only occurs when:
* The object has one or more fields with SerializeReference attribute.
* The object has a field named "references"

Workaround: rename a member with name "references" to anything else
