Fix CSV export

[kmcginnes]

Description

This type error was happening because when we call the accessor to get the cell data for the row we could be passing either the row data or a wrapper object that contains the row data in one of its properties.

Since no logic required any of the data in the row wrapper, it made sense to move the check of what type of data we have up a level. So I added a new map before the big map logic to make sure we always have the row data and not the wrapper.

Types

I updated the generic constraints across the board to match what React Table expects. This helped me find the issue with the row and row wrapper.

While these changes aren't necessary for the fix, I think they improve the code quality and will help find future issues.

Automated testing

This logic is super complicated and interwoven. I'd love to have it under some tests. But in the interest of time I haven't added any in this PR.

If we consider it important enough, we can add a new GitHub issue to add some tests as a follow up change.

Validation

1. Open the browser's developer console
2. Add a node to the graph
3. Open the table view at the bottom
4. Choose export with all columns selected
5. Make sure the "Keep filtering and sorting" checkbox is checked
6. Click "Export"
7. See failure in the console
