ResolveAll doesn't check if implementations are in the container already

[togakangaroo]

c.Register<T1>().AsSingleton();
c.RegisterMultiple(typeof(I1), new[] { typeof(T1) });
Assert.AreEqual(c.Resolve<T1>(), c.Resole<I1>().First())

the implementating types should be resolved from the container as well.

I'm basically doing this and it is failing

• register several UIs as singletons
• all UIs implement an interface - RegisterMultiple this interface to all UIs
• resolve select UIs and show them
• ....later
• all UIs via the interface and dispose of them
