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.

Fix bug #5 DBContext in unit tests
166f19b 
DbContext Core requires DI Logging, but only referencing
Microsoft.AspNetCore.Components.Web breaks the LoggerFactory
on runtime with MissingMethodException.

SetUpDbContext() in tests now set up a test-specific ServiceProvider
with the NullLoggerFactory which gets applied by
optionsBuilder.UseInternalServiceProvider(ServiceProvider).

Update EF Core to 5.0.17
