Issue

The integration tests are not collecting all logs of all methods of test classes.
As an example, check the simple_replication tests, only its first method has its log collected. The same behavior happens in Jenkins, so it's not related to PR CI or Jenkins, but to the code itself.

Steps to Reproduce

1. Run a integration test (ipatest/test_integration/*)

Actual behavior

1. Check that the logs from some methods are not collected

Expected behavior

Logs should be collected

Additional info:

We have the @tasks.collect_log decorator, however, it should not be necessary to call it everywhere, since the code it's already being called.
