Fix tests that are using SocialActivity framework

Because SocialActivity framework is using different transactions to store data (social activity counters and social activity settings), Testing Infrastructure is not able to do rollback of every element in the transactions that are created inside the test.

For that, a developer using Transactional listener will believe that every created element is rolled back. But it is not.

Because of that, this kind of tests cannot use TransactionalExecturitionTestListener and Transactional anotation and the developer have to remove/delete all created data in an after method/class strategy.
