How to reproduce:
1. Open the attached project "case_1215642-SerializeReference"
2. Open the Scene "SampleScene"
3. Press the Play button
4. Observe the results in the Console window

Expected results: there are no errors in the Console window
Actual results: errors occur in the Console window such as "A scripted class has a different serialization layout when loading." and "A scripted object (probably Game.TestScript?) has a different serialization layout when loading."

Reproducible with: 2019.3.0f2, 2019.3.0f6, 2020.1.0a15, 2020.1.0a22
Not reproducible with: 2019.3.0f1, 2020.1.0a14

Could not test with: 2017.4, 2018.4, 2019.2, 2019.3.0a12 because " 'SerializeReference' is inaccessible due to its protection level

The issue occurs if you have an empty collection of a type containing an array of with an element type containing itself a Serialized Reference.
