5182: Remove hard coded task ids to prevent flaky tests r=irevoire a=mhmoudr

# Pull Request

## Related issue
Fixes partial #4840

## What does this PR do?
- Mainly scan the test code for any hard coded task Id and replace it by the returned task Id once the action or task is performed on an index.
- PS: _PR is not split by files as it has one theme applied to all tests which make it easy to review_
