[fix] #2202: Fix total field in query response

[Erigara]

Signed-off-by: Shanin Roman shanin1000@yandex.ru

Description of the Change

The total is the number of values returned in the top-most level of an iterable container after applying filter and before pagination.

• Fix total field calculation in handle_queries;
• Extend test torii_pagination to check that total field value is unaffected by pagination.

Issue

Closes #2202.

Benefits

The total field is now what the SDK developers expect.

Possible Drawbacks

None.

Usage Examples or Tests

cargo test --package iroha --lib -- torii::tests::torii_pagination --exact --nocapture

@arndey Should we also include the number of filtered-out results in the total?
