Add pagination to Lesson and Quiz resource navigation to handle unnecessarily large topics

[MindfulQA]

Observed behavior

While attempting to view a topic's contents to add to a lesson, the app crashed.

It seems likely that this is caused by opening a topic with too many children.

Expected behavior

The user should be able to view a topic's contents.

Errors and logs

Note: these two are identical, but one is a PDF and the other is a .docx - it wouldn't let us upload the isolated copied version in the RTF format it was in, so we wanted to provide two file types in case one is preferable:

(This ticket is for the second crash within the log below)

Here's a .txt version of the full log from this session:

The crash happened between 10:50pm and 11pm Pacific time on October 27th.

This is the debut.txt file, which doesn't really contain anything -- but attaching per request, if only to note that it is indeed empty.

Steps to reproduce

Note: this is not 100% reproducible, and appears to be somewhat of an edge case. But these were the steps taken:

1. Open Kolibiri desktop app and log in to Coach account
2. From the class home page, click on an existing lesson (or create a new one if there is not one already existing)
3. The lesson should open under the "Reports" tab. From the lesson title box, click the "options" drop-down menu and click "manage resources."
4. Click on a content channel
5. Enter a search term in the search bar and click the magnifying glass
6. Observe the results
7. Click "Exit Search"
8. Click on a topic and view the list of content/resources (note: not positive which topic was clicked, as it crashed so quickly and unexpectedly)
9. Observe app crash
   (not 100% reproducible)
