Increase AWS unit test coverage

[javiersanchz]

Affected integration
AWS

Description

• During the release of 4.8.0 - RC 1, the coverage percentages of the unit tests for the AWS module in s3_log_handler.py and sqs_message_processor.py are low, as can be seen at Release 4.8.0 - RC 1 - Python unit tests #23300 (comment). We should add test cases to increase it.

• Another script to consider is wodles/utils.py with a percentage of 53%.

Checks

• Unit tests without failures and related coverage reports.
• Documentation.
• Integration test mapping (using api/test/integration/mapping/_test_mapping.py).

Update

The files mentioned have a 87% and 97% coverage as it can be checked in the latest pytest unit tests coverage report. I added unit tests for the utils.py file and removed some unused methods.
