.NET Core DbContext defunct in unit tests

[toniarnold]

Since a forced upgrade to .NET 5 (for Blazor .NET 6), DbContext Core requires DI Logging, thus unit tests requiring DbContext fail in the VS Test Explorer.

As soon as asplib.blazor gets referenced in test.core, we get a MissingMethodException at LoggerFactory.Create(). If the reference is only removed, the DbTest tests using DBContext pass. Problem is the reference to Microsoft.AspNetCore.Components.Web.

Fixed with commit 166f19b
