Description

If a project has built a dedicated server executable then it will fail when trying to convert the project from 4.7.6 to 4.8.

EDIT:
Following the steps on the wiki page for Dedicated Servers () in 4.8 will cause the project to fail compile completely. The <project>Server.Target.cs seems to cause issues in 4.8

Steps to Reproduce

1. Create new code project in 4.7.6 named DedicatedServerTest
2. Download attached zip file
3. Place "DedicatedServerTestServer.Target.cs" in the project's Source folder
4. Right click on the .uproject and select Generate Visual Studio project files
5. Open .sln and set Solution Configuration to DevelopmentServer
6. Build the project
7. Right click on the .uproject and select Switch Unreal Engine version

Result:
Engine version conversion fails due to UBT not containing definition for 'BuildingRocket'

Expected:
Projects with dedicated server set up can be converted from 4.7 to 4.8
