account_objects method does not return NFTokenPages (Version: 1.9.4)

[nixer89]

Issue Description

When trying to get an xrpl accounts owned objects, the method account_objects does not return NFTokenPage(s). This is a problem because one could not reliably show the user which objects currently count towards his owner reserve.

The documentation also states:
The account_objects command returns the raw [ledger format](https://xrpl.org/ledger-object-types.html) for all objects owned by an account.

Steps to Reproduce

1. call the account_objects method of an account which owns some NFTs
2. response does not include any NFTokenPage

Expected Result

Also NFTokenPages are returned through the account_objects method.

Actual Result

No NFTokenPage is returned

This is actually quite a problem. On accounts with NFTs, the OwnerCount of the AccountRoot objects shows a bigger number than objects are returned by the account_objects method. This confuses developers as well as users.

Here is a code solution: https://github.com/RichardAH/rippled/tree/nftpage_accobjs

I have tested by hand but it needs unit tests to go in. If someone wants to provide those then we can PR it.

Why can't this just be done client side?

Thanks! will do today!

I actually have a client side solution. It is very hacky indeed. Curious to see if you can figure out what it is before I share it
