RegisterTypes extension ignoring 'overwriteExistingMappings' flag

[BigPeeg]

If a type is registered in a Unity container where the interface and class follow the same pattern as used in 'registration by convention', when the RegisterTypes extension is used to register by convention, the original mapping is over-written despite the 'overwriteExistingMappings' flag of the extension method being set to 'false'.

`

        var container = new UnityContainer();
        container.RegisterType<IAppTester, AppTester>(new PerThreadLifetimeManager());

        container.RegisterTypes(
            AllClasses.FromLoadedAssemblies(),
            WithMappings.FromMatchingInterface,
            WithName.Default);

        container.Registrations.First(r => r.RegisteredType.Equals(typeof(IAppTester))).LifetimeManager.GetType().Should().Be<PerThreadLifetimeManager>("specifically registered type should remain");

I would need a unit test to reproduce the error
