Wrong type resolving on version 1.6.0 and 1.6.1

[yevgenchepurko]

Dear, Bernhard Richter.

Thank you for your work on LightInject.Microsoft.Hosting and other components.
Here is an issue that we've encountered with LightInject.Microsoft.Hosting.

With version 1.5.3

having setup

serviceRegistry.RegisterScoped<IA>(f => new A1());
serviceRegistry.RegisterScoped<IA>(f => new A3(), nameof(A3));
serviceRegistry.RegisterScoped<IA>(f => new A2(), nameof(A2));

the resolution

host.Services.GetService<IA>();

Resolved to Type A1 - unnamed instance.
But with latest version 1.6.1 it resolves into A3, it started with version 1.6.0

Please find attached test project demonstrating the issue.
