[BUG] Pagination in V2 doesn't track mapping change

[Yury-Fridlyand]

What is the bug?

Columns added to the table (index) aren't queried.

How can one reproduce the bug?

Steps to reproduce the behavior:

1. Create an empty index

PUT http://localhost:9200/pmtest

2. Add few docs

POST http://localhost:9200/pmtest/_doc?refresh=true
{
    "age": 30
}
POST http://localhost:9200/pmtest/_doc?refresh=true
{
    "age": 32
}

3. Starting paging

POST http://localhost:9200/_plugins/_sql
{
    "query": "SELECT * from pmtest",
    "fetch_size": 1
}

4. Add a doc with another field

POST http://localhost:9200/pmtest/_doc?refresh=true
{
    "name": "pewpew"
}

5. Keep paging till the end

What is the expected behavior?

Last doc should be returned as well

What is your host/environment?

feature/pagination/P1 @ 7dd445c

Do you have any additional context?

Project list should be refreshed on every request

Fixed in f27f891 and 3c32eea in #1500 - I serialize includes as a part of cursor. Maybe that fix should be reworked.
