AssemblyInitialize/Cleanup should not be executed when all tests are ignored

Describe the bug

When all tests in the project are ignored, the AssemblyInitialize method is not executed. The AssemblyCleanup is always executed. I’d expect both methods to always execute or not execute. The answer to this issue suggests the AssemblyCleanup will always execute, so I expect the same from AssemblyInitialize (otherwise, what the cleanup method supposed to clean?)

Steps To Reproduce

Set the breakpoint in AssemblyInitialize and AssemblyCleanup and debug

[TestClass]
public class UnitTest1
{
    [AssemblyInitialize]
    public static void AssemblyInitialize(TestContext context)
    {
    }

    [AssemblyCleanup]
    public static void AssemblyCleanup()
    {
    }

    [TestMethod, Ignore]
    public void TestMethod1()
    {
    }
}

Expected behavior

Both AssemblyInitialize and AssemblyCleanup are executed

Actual behavior

Only AssemblyCleanup is executed

Skipping both is even better. I see no point in initializing something that won’t be used, especially if it’s a heavy operation like creating and initializing DB, for example.

@Evangelink I can repro in these versions 2.2.10, 2.2.8, 2.2.4.
