Two refactors with the same name are hard to test

TypeScript Version: nightly (2.6.0-dev.20170929)

Code

/// <reference path='fourslash.ts' />

////function f() { /*a*/1/*b*/; }

goTo.select("a", "b");
edit.applyRefactor({
    refactorName: "?",
    actionName: "?",
    actionDescription: "?",
    newContent: "?",
});

Running this test with the change in #18843 prints:

     Error: At line 1, col 15: The expected refactor: ? is not available at the marker location.
Available refactors: Extract Symbol,Extract Symbol

Problem: The way applyRefactor in fourslash.ts is written, there's no way we can assert things about the second refactor, since we match them by name and we'll always find the first one first. (Also, this seems to uncover that we have no tests of it.)

Instead of making the test runner more complicated, we should probably have one refactor with multiple actions, or two refactors with different names.

I believe they're distinguished using actionName. The refactorName tells it which getEditsForAction implementation to call and the actionName tells it which action to take.
