Fix #115: typeof usage on object types

[SebastienGllmt]

See #115 for the description of the problem and how I got to the solution

This is the final generated code which looks correct 👍

"use strict";
Object.defineProperty(exports, "__esModule", { value: true });
exports.Status = void 0;
const assert = require("assert");
const index_1 = require("../index");
/* https://github.com/woutervh-/typescript-is/issues/115 */
exports.Status = {
    enable: 'enable',
    disable: 'disable'
};
describe('is', () => {
    describe('Accessing generic member of a type', () => {
        it('should return true for the right member', () => {
            assert.deepStrictEqual(index_1.is({ status: exports.Status.enable }, object => { function _1(object) { ; if (object !== "enable")
                return {};
            else
                return null; } function _0(object) { ; if (typeof object !== "object" || object === null || Array.isArray(object))
                return {}; {
                if ("status" in object) {
                    var error = _1(object["status"]);
                    if (error)
                        return error;
                }
                else
                    return {};
            } return null; } return _0(object); }), true);
        });
        it('should return false for the wrong member', () => {
            assert.deepStrictEqual(index_1.is({ status: exports.Status.disable }, object => { function _1(object) { ; if (object !== "enable")
                return {};
            else
                return null; } function _0(object) { ; if (typeof object !== "object" || object === null || Array.isArray(object))
                return {}; {
                if ("status" in object) {
                    var error = _1(object["status"]);
                    if (error)
                        return error;
                }
                else
                    return {};
            } return null; } return _0(object); }), false);
        });
    });
});
