Exception: Multiple instances of SignalBus found

[pilzinho]

Hello!

I posted the issue we have also in the Zenject repo (ssannandeji#656) but it can be reproduced with Extenject 8.0.1 as well.
When loading 3 scenes each with a SceneContext and parented using Contract Names and the SignalBus installed in the first scene we get the following exception when the third scene is loaded:

ZenjectException: Found multiple matches when only one was expected for type 'SignalBus' while building object with type 'SignalBus'. Object graph:
SceneKernel
DisposableManager
SignalBus

The second and third scene each install a component which gets the SignalBus injected.
I have created a simple project to reproduce the error. I'm on Windows 10 with Unity 2018.4.3f1 with Extenject 8.0.1.
To run the project open it in Unity and add 'Zenject-WithSampleGames@v8.0.1.unitypackage
' (the GameSignalsInstaller from the sample game is used in the test project). The main scene is called 'SignalBusIssueScene1' located in the folder 'SignalBusIssue'.
I also attached the output log from the build so you can see the whole stack trace of the exception.
