No-unused-expression wrongly lints a comma-separated expression.

[ChiriVulpes]

Bug Report

• TSLint version: 4.3.1
• TypeScript version: 2.1.5
• Running TSLint via: Visual Studio Code

TypeScript code being linted

let x: number, y: number;
x = 1, y = 2;

with tslint.json configuration:

{
    "rules": {
		"no-unused-expression": true
	}
}

Actual behavior

Line 2 lints with expected an assignment or function call

Expected behavior

Line 2 contains two assignments, so it should not be linted.

Why not just use x = 1; y = 2;?

Doesn't work on one line if statements.
