Issue Description

In a jsdom environment, any test that directly or indirectly imports parse (or parse/node) gets terminated due to an UnhandledPromiseRejection. Mocking with jest.mock doesn't help.

The error message is "ReferenceError: indexedDB is not defined"

Steps to reproduce

Run this test:

/*
 * @jest-environment jsdom
 */
import Parse from 'parse'; // or 'parse/node'
jest.mock('parse'); // or don't, it doesn't make a difference

describe('a test', () => {
  it("shouldn't break just because we import the parse module", () => {
    expect(1).toBe(1);
  });
});

Actual Outcome

node:internal/process/promises:246
          triggerUncaughtException(err, true /* fromPromise */);
          ^

[UnhandledPromiseRejection: This error originated either by throwing inside of an async 
function without a catch block, or by rejecting a promise which was not handled with .catch(). 
The promise rejected with the reason "ReferenceError: indexedDB is not defined".] {
  code: 'ERR_UNHANDLED_REJECTION'
}

Process finished with exit code 1

Expected Outcome

Test passed (expect(1).toBe(1)).

Notes

Outside of a jsdom environment, this error doesn't happen. (You can verify this by running the same test without the @jest-environment decorator at the top.)

So maybe the parse SDK is checking for window or document, or something else that jsdom provides, and then expecting something else that jsdom doesn't provide?

But the issue also occurs if you import parse/node instead of parse—ie, when the SDK shouldn't be expecting a browser environment.
