[Task] Update Cypress Tests for Query.spec.js

[giranm]

Summary

Since introduction of change request #132, we have added a 2000ms debounce when any of the query filters have been updated. Although this gives users a chance to update their filters in quick succession (without exhausting API calls), this may be the cause of why some of the integration tests are failing.

Example failed run: https://github.com/giranm/pd-live-react/runs/7467993657?check_suite_focus=true#step:7:75

Proposed Fix

Introduce a 2000ms wait on waitForIncidentTable() under cypress/support/util/common.js before the incident table element is queried. This should give enough time for PD Live to call the API and to re-render the correct data.
