fix: deleting records in query builder has a minimum of zero results

[kwhuber]

Fixes #4988

This PR introduces a change to fix a ui issue when a user deletes records through the query builder. Before the change, after deleting the last record in a specific query, the results header would incorrectly return as Results: (-1). After the change, the results header will only show Results: (0) when the last record is deleted.

This change is in the following line:

specify7/specifyweb/frontend/js_src/lib/components/QueryBuilder/Results.tsx

Line 172 in 81f9974

totalCount === undefined ? undefined : Math.max(0, totalCount - removeCount)

This prevents a negative account from showing up in the results header.
