vaadin.productionMode must be set after devsoap credentials or compatibility mode are set

[johndevs]

Desktop (please complete the following information):

• OS: Ubuntu
• JDK version: JDK 11
• Gradle version: 6.0.0
• Vaadin Plugin version: 1.3.1 Describe the bug Setting vaadin.productionMode before setting devsoap.email will not enable production mode. instead an error message is showed. Inversing the order works.

To Reproduce

Using this fails:

vaadin {    
    productionMode = true
}
devsoap {
    email = ...
    key =...
}

While this works:

devsoap {
    email = ...
    key =...
}
vaadin {    
    productionMode = true
}

The same is if you set production mode before compatibility mode and you are unlicensed.

So using this will fail:

vaadin {    
    productionMode = true
    compatibilityMode = true
}

While this will work

vaadin {    
    compatibilityMode = true
    productionMode = true
}
