rCOMM0348a8fba605: [services] Tests - Update backup test

Summary

Depends on D4324

linear task: https://linear.app/comm/issue/ENG-1288/properly-handle-the-dynamodb-item-size-limit

I added a case when we first add an item, it is stored in the database, then we add so many attachment holders, that it goes beyond the dynamo limit and we move this data to the S3.

Test Plan

cd services
yarn run-integration-tests backup

17 ↗	(On Diff #13660)	According to https://doc.rust-lang.org/book/ch07-04-bringing-paths-into-scope-with-the-use-keyword.html#creating-idiomatic-use-paths it is a good practice to not import a function directly - we should instead import its parent module. Bringing the function’s parent module into scope with use means we have to specify the parent module when calling the function. Specifying the parent module when calling the function makes it clear that the function isn’t locally defined while still minimizing repetition of the full path. On the other hand, when bringing in structs, enums, and other items with use, it’s idiomatic to specify the full path.
134 ↗	(On Diff #13660)	Not sure what's better, but when creating an empty vector we can simply use a constructor
135 ↗	(On Diff #13660)	It would be a good idea to connect two magic numbers `500` and `300`, so that changing one would cause the other one to be changed. We can e.g. create a variable for `300` and use that variable + 200 here.
151 ↗	(On Diff #13660)	What do you think about using `enumerate` here?
154 ↗	(On Diff #13660)	`assert_eq`?

17 ↗	(On Diff #13660)	ok, I'm good with this.
134 ↗	(On Diff #13660)	I can change this, I don't think that matters.
151 ↗	(On Diff #13660)	I think that would be confusing. We're using data from two collections at the same time. We'd need to access one by index and the other one by name (name used in the for loop taken from the enumeration).
154 ↗	(On Diff #13660)	right

155–162 ↗	(On Diff #14034)	Not sure if specifying `expected` and `from_result` twice makes sense
167–190 ↗	(On Diff #14034)	This code is copied from 30 lines above it - could you find a way to avoid this duplication?
