[Bug]: Incorrect integration test lifecycle order

[ShawnTheBeachy]

Description

In the docs it says that Factory.ConfigureWebHost is supposed to run as step 3, then ConfigureTestConfiguration as step 5. However, I'm seeing different behavior; my ConfigureTestConfiguration method is being executed before Factory.ConfigureWebHost, meaning that I'm unable to override the app config.

Expected Behavior

The methods should run in the order the documentation says they do.

Actual Behavior

The methods do not run in the order the documentation says they do.

Steps to Reproduce

public abstract class TestsBase : WebApplicationTest<WebApplicationFactory, Program>
{
    protected override void ConfigureTestConfiguration(IConfigurationBuilder config)
    {
        // Should run as step 5.
    }
}

public sealed class WebApplicationFactory : TestWebApplicationFactory<Program>
{
    protected override void ConfigureWebHost(IWebHostBuilder builder)
    {
        // Should run as step 3.
    }
}

IDE-Specific Issue?

• I've confirmed this issue occurs when running via dotnet test or dotnet run, not just in my IDE

Correction: ConfigureTestConfiguration actually seems to run twice: once before the factory method, and once after.
