[Test] Add tests for async progress queue worker

[JckXia]

Resolves #1043.

Similar to PR #1307 but for AsyncProgressQueueWorker

Looks good! This covers the remaining untested methods listed in #1043.

Just a couple of small changes. Take a look at my comments (they are applicable to multiple locations in the code as well).

Guess I didn't catch these in #1307 ... whoops 😅

No need for noop arg for mustCall.

[KevinEady]

The common.mustNotCall() should be the Promise's reject callback, and the resolve() belongs inside the hooks.then() callback after the assertion.

This will provide the actual assertion error (in case of failure). Try changing the assertion object, eg. the destroy event name to __destroy.

With your code, you'll get:

> AssertionError [ERR_ASSERTION]: function should not have been called
    at mustNotCall (/Users/kevineady/Documents/Projects/node-addon-api/test/common/index.js:120:12) {
  generatedMessage: false,
  code: 'ERR_ASSERTION',
  actual: undefined,
  expected: undefined,
  operator: 'fail'
}

With the suggested changes, you'll get:

AssertionError [ERR_ASSERTION]: Expected values to be strictly deep-equal:
+ actual - expected ... Lines skipped

  [
    {
...
    },
    {
+     eventName: 'destroy'
-     eventName: '__destroy'
    }
  ]
    at /Users/kevineady/Documents/Projects/node-addon-api/test/async_progress_queue_worker.js:41:14 {
  generatedMessage: true,
  code: 'ERR_ASSERTION',
  actual: [Array],
  expected: [Array],
  operator: 'deepStrictEqual'
}

Sorry for the wait. Thank you for pointing this out! I borrowed this pattern from other places in the test suites. Will draft up another PR to make these fixes.

LGTM !
