Can't access the properties of a custom emulator

[Leo Arias]

I have created a custom emulator that inherits from CustomEmulatorBase, and I'm using it while launching the application.
When I try to access a property from one of the classes that inherit from that emulator, I get

AttributeError: 'NoneType' object has no attribute 'introspection_iface'

This is because the class used as an introspection object has no _Backend.

We should copy the _Backend from the default introspection object, or create a new one for this custom one. I'm not sure how to do this.

I've linked a branch with the test that throws this error.

With this I can make the test pass:

But it makes the other two fail, so I left it worse than before :D
