Completion sugests items that do not satisfy generic constraint

[pakrym]

Version Used: Version 16.5.0 Preview 1.0 [29501.166.master]

Steps to Reproduce:

1. Create Console app
2. Add Azure.Storage.Blobs Nuget package
3. Open intellisense on args.

Expected Behavior:

Extension methods that don't satisfy the generic constraint are not shown.

Actual Behavior:

AddBlobServiceClient is shown

        /// <summary>
        /// Registers a <see cref="BlobServiceClient"/> instance with connection options loaded from the provided <paramref name="configuration"/> instance.
        /// </summary>
        public static IAzureClientBuilder<BlobServiceClient, BlobClientOptions> AddBlobServiceClient<TBuilder, TConfiguration>(this TBuilder builder, TConfiguration configuration)
            where TBuilder : IAzureClientFactoryBuilderWithConfiguration<TConfiguration>
        {
            return builder.RegisterClientFactory<BlobServiceClient, BlobClientOptions>(configuration);
        }

That does not look like native VS IntelliSense. Is that Resharper?

My bad, reproes with R# disabled:

@ivanbasov This sounds like #37780 but was reported on 16.5 internal preview.

@gafter this maybe related with #38109 . Maybe more work should be done on the compiler side. Please take a look.
