Fix bug with "every funk" in private class function

[pokey]

Here's a file that triggers the error. Say "take every funk" when cursor is in private function at the bottom

import * as vscode from "vscode";
import { join } from "path";
import { COLORS } from "./constants";
import { SymbolColor } from "./constants";

export type DecorationMap = {
  [k in SymbolColor]?: vscode.TextEditorDecorationType;
};

export interface NamedDecoration {
  name: SymbolColor;
  decoration: vscode.TextEditorDecorationType;
}

export default class Decorations {
  decorations: NamedDecoration[];
  decorationMap: DecorationMap;

  constructor() {
    const iconWidth = "1rem";
    const iconPath = join(__dirname, "..", "images", "hat.svg");

    this.decorations = COLORS.map((color) => ({
      name: color,
      decoration: vscode.window.createTextEditorDecorationType({
        // borderStyle: "solid",
        // borderColor: new vscode.ThemeColor(`cursorless.${color}Border`),
        // borderWidth: "2px 0px 0px 0px",
        // borderRadius: "4px",
        // backgroundColor: new vscode.ThemeColor(`cursorless.${color}Background`),
        rangeBehavior: vscode.DecorationRangeBehavior.ClosedClosed,
        after: {
          margin: `-1rem 0 0 -${iconWidth}`,
          width: iconWidth,
          height: iconWidth,
          color: new vscode.ThemeColor(`cursorless.${color}Border`),
          contentIconPath: iconPath,
        },
      }),
    }));

    this.decorationMap = Object.fromEntries(
      this.decorations.map(({ name, decoration }) => [name, decoration])
    );
  }
  private constructWrapperSvg() {
    const svg = `<svg xmlns="http://www.w3.org/2000/svg" height="24px" viewBox="0 0 24 24" width="24px" fill="currentColor"><path d="M0 0h24v24H0V0z" fill="none"/><path d="M19 13H5v-2h14v2z"/></svg>`;
    return vscode.Uri.parse(`data:image/svg+xml;utf8,${svg}`);
  }
}

Not sure if related but the following doesn't work:

class TestCase {
  talonCommand!: string;

  extractPrimitiveTargetKeys() {}
}

If you say "take funk" with your cursor in extractPrimitiveTargetKeys, you get an error Cannot read property 'type' of null.

Strangely the following works so maybe it's just a tree-sitter error

class TestCase {
  talonCommand: string = "";

  extractPrimitiveTargetKeys() {}
}

All of these things now work for me, so they were probably fixed when @AndreasArvidsson was hacking on our typescript pattern matchers 👍👍
