explicitly setup test scenario for test_query_default_page_limit (#18393

)

## Description 

Unblock #18277 by explicitly
setting up the correct test scenario for the
`test_query_default_page_limit` test.

I think we can follow this up with 
1. instead of using the same db url, follow sui-graphql-e2e-tests
pattern and generate unique db urls for each test
2. this is so that we can run tests in parallel instead of sequentially
(which is the case today due to the serial)
3. we can leverage ExecutorCluster.cleanup_resources to cleanup each
test



## Test plan 

How did you test the new or updated feature?

## Release notes

Check each box that your changes affect. If none of the boxes relate to
your changes, release notes aren't required.

For each box you select, include information after the relevant heading
that describes the impact of your changes that a user might notice and
any actions they must take to implement updates.
