2.1 Regression: Definite assignment with try..finally

[jods4]

TypeScript Version: 2.1.? / the one that comes with VS 2017 RC

Code

async function bug() {
    let response: Response;
    try {
        response = await fetch("www.google.com");
    }    
    finally {
    }
    if (response.ok)  // <- error: Variable response is used before being assigned
        console.log("ok");
}

Expected behavior: was compiling (and working) fine in TS 2.0

Actual behavior: Error: response is used before being assigned.

looks like a duplicate of #12205

I didn't see that one, it looks like a dup indeed.
