Fix a logical flaw when deleting a build in the jenkins_build module (#5514)

* Fix the logical flaw when deleting a build in the jenkins_build module.

* Fix the logical flaw when deleting a Jenkins build in the jenkins_build module.

* Adding changelogs.

* Update tests/unit/plugins/modules/test_jenkins_build.py

Co-authored-by: Felix Fontein <felix@fontein.de>

* Attempt to mock the exception classes.

* Remedy the CI issues when mocking the exception classes.

* Assuming a way to mock the get_build_status function.

* Near to the feasible approach.

* Calls the correct class when unit testing.

* Fix sending wrong arguments when unit testing.

* Directly assign the argument value in the unit testing.

* Fix errors calling different classes.
