Give 'this' keyword suggestion the same `sortText` as class properties if inside a class

From microsoft/vscode#66868

TypeScript Version: 3.4.0-dev.20190220

Search Terms:

• suggestions
• completions
• sortText

Code
For the javascript:

class Foo {
    constructor() {
        this.prop = 1;
    }

    render() {
        th
    }
}

• Trigger intellisense after th in render

Expected behavior:
this should be the first suggestion in VS Code

Actual behavior:
render and then prop are the first suggestions

The root cause of this is that the suggestion for this has a sortText of "0" while the one for prop and render have a sortText of "1". This causes VS Code to sort prop and render before this

@amcasey @minestarks I'm not sure if the current sorting issue would also effect VS

@mjbvz I couldn't tell whether your example was in JS or TS, but I wasn't able to repro either in VS - both suggest this.

I don't think any more information is needed on this issue. I just wanted to under if VS and VS Code use different sorting logic internally. On the VS Code side, we do use the sortText when prioritizing completions
