5210: Improve test performance of get_index.rs  r=irevoire a=DerTimonius

# Pull Request

## Related issue
related to #4840

## What does this PR do?
This PR aims to improve the performance of the tests in `get_index.rs`.

There is a small issue though: 
the `list_multiple_indexes` test works great when ran alone, but when running with other tests it fails with a `corrupted task queue` error. I guess this has something to do with using a shared server, but I was not really able to pinpoint the issue.

Also, the `no_index_return_empty_list` does not work a shared server (as there now will always be at least one index on the server) and I was not really sure if rebuilding the whole suite for `get_and_paginate_indexes` should be viable? While waiting for feedback on the issue mentioned above, I'll try to change the `get_and_paginate_indexes` test so that it can use the shared server
