      Introduce a pattern for fully typed store modules · 9d40fff9
      Robert Knight authored 
      Introduce a pattern for creating store modules which are fully typed,
using the "activity" module as a test case / example. This allows
TypeScript to check both external usage of the module, as well as
internal consistency between the different elements of it (initial
state, reducers, action creators, selectors).

The elements of this pattern are:

 - A `State` type is defined in each module, which is typically whatever
   shape the module's initial state has.

 - Each function in the `reducers` map specifies the type of its `state`
   parameter as `State` and defines the fields of the action.

 - Action creators use a new `makeAction` helper, which ensures that the
   type of dispatched actions matches what the reducer expects

 - The `createStoreModule` helper ties all the elements of the module
   (reducers, actions, selectors) together and makes sure they are
   consistent with one another.

The general structure of a typed store module, to which the various existing
modules will converge, is:

```js
import { createStoreModule, makeAction } from '../create-store';

const initialState = { ... }

/** @typedef {typeof initialState} State */

const reducers = {
  /**
   * @param {State} state
   * @param {{ id: string }} action
   */
  SOME_ACTION(state, action) {
    ...
  }
}

/**
 * @param {string} id
 */
function someAction(id) {
  return makeAction(reducers, 'SOME_ACTION', { id });
}

/**
 * @param {State}
 */
function someSelector(state) {
  ...
}

export someModule = createStoreModule(initialState, {
  namespace: 'someModule',
  reducers,
  actionCreators: { someAction },
  selectors: { someSelector },
});
```

      Reset callback before checking for absence of call · d5ace953
      Robert Knight authored 
      This pattern makes it clearer that we are testing for a callback not
being invoked after a sequence of events.

      Fix issues that could cause unexpected `onDocumentReady` firing · f7ab8ac0
      Robert Knight authored 
      Fix various issues that could cause the callback to `onDocumentReady` to
fire after the subscription had been canceled.

 - `pollOnUnload` was called twice for the initial document, once at the
   top level of the function and once by the first call to
   `checkForDocumentChange`. This resulted into "unload" listeners being
   added for the same window.

 - The initial async `checkForDocumentChange` call would still fire if
   the subscription was immediately canceled

 - If the current window's "unload" event fired after the subscription
   was canceled, polling would be restarted, effectively re-subscribing
   to document changes.
