Regression

Yes

Prefabs lose references to unnamed meshes after upgrading the project to 2019.1.0a10 and above

Asset Importers

-

How to reproduce:
1. Open the attached project ("bugreport.zip")
2. Open the repro scene ("SampleScene")
3. Notice the building in the scene view
4. Select the "testbug" object in the Inspector (it is a child of the Main Camera)
5. Note that its children objects reference meshes with no name
6. Close the project and upgrade it to 2019.1.0a10 or above
7. Inspect the scene view and the "testbug" object

Expected results: Building can be seen in the scene, "testbug" still has references to the meshes
Actual results: "testbug" object and its prefab loses references to the unnamed meshes

Reproducible with: 2019.1.0a10, 2019.1.0f2, 2019.2.0a13
Not reproducible with 2017.4.26f1, 2018.3.14f1, 2019.1.0a9

Notes:
1. Upgrading the project from 2017.4 to 2018.3 does not reproduce the issue
