Regression - started to appear in 2017.1.0b2, but everything is good in 2017.1.0b1
When open "Tanks!!! Reference Project" project from A$ in 2017.1.0b2 and connect through MatchMaker - Editor part doesn't work

How we can reproduce it
1 Create new project
2 Go to AssetStore and find "Tanks!!! Reference Project" (https://www.assetstore.unity3d.com/en/#!/content/80165)
3 Import this package to your project
or
just open attached project
4 Start host in Editor
5 Build and Run Standalone and connect it as Client

--- please see attached video (TanksRefProjectProblem.swf) with the explanation ---

Actual result: second tank (spawnable object) doesn't appear in the Editor instance (Host), but everything works fine in Standalone (Client). Somehow "OnNetwirkDestroy" is called on second tank object...
!!! When start Host in Standalone and Client in Editor - everything works fine !!!

Expected results: there should be 2 tanks (spawnable object)
