ConfigFileDiag event is not sent after tsconfig.json is saved

[dbaeumer]

TypeScript Version: 2.0.6
Code

tsconfig.json

{
    "compilerOptions": {
        "module": "commonjs",
        "target": "es5",
        "aaaca": true
    }
}

• open a TS file covered by above tsconfig.json

Observe: you get an event

[Trace - 2:35:24 PM] Event received: configFileDiag (0).
Data: {
    "configFile": "c:/Users/dirkb/Projects/mseng/VSCode/Playgrounds/ts-2.0/tsconfig.json",
    "diagnostics": [
        {
            "text": "Unknown compiler option 'aaaca'."
        }
    ]
}

• make the tsconfig.json file correct (e.g. remove the "aaaca" property.

Observe: no configFileDiag event is sent. No event is send either if you do changes that make the tsconfig.json file still incorrect.

@mhegazy @zhengbli could you please investigate this for VS Code 1.7. I disabled the tsconfig file error checking for now.
