Fakes: Naming conflict for `type_` variables

[glureau]

Given 2 classes with same name on 2 different packages, the generated code will be:

import a.b.c.di.DeviceOsFamily as DiDeviceOsFamily
import a.b.c.model.DeviceOsFamily as ModelDeviceOsFamily

private val type_DeviceOsFamily: KType = typeOf<DiDeviceOsFamily>()
private val type_DeviceOsFamily: KType = typeOf<ModelDeviceOsFamily>()

The prefix used in import aliases should also be used for variable names I guess.
