Query > Pagination: The preference overallCount was not effective

[heapwalker]

According to the docs https://docs.skygear.io/js/guide/query#pagination-ordering, under the sub-section Counting the records,

To get the number of records matching a query, set the overallCount of the Query to true.

However, by real experiment, there was nothing at the second arguments of the success callback, e.g.:

query.overallCount = true;
skygear.publicDB.query(query).then(function(records, overallCount) {
    console.log('overallCount: ', overallCount);
});

it yields:

overallCount: undefined

I think the example in the documentation does not match our implementation. The expected usage would be:

query.overallCount = true;
skygear.publicDB.query(query).then((notes) => {
  console.log('%d records matching query.', notes.overallCount);
}, (error) => {
  console.error(error);
});

Great. We can get the overallCount correctly.

Would you keep current implementation and modify the docs?

@cpryanpang I would update the documentation.
