Fixed adding of aspectJ-line for IT if onlyOneCallRecording is set

• You can register IT with "tasks.register('integrationTest', Test) {...}" also. In this case it was not recognized, that module has IT-task.
• testBlock was put inside IT-block, fixed this
• had to add IT-block and adaptTask for IT if build.gradle had no integrationTestLine but IT-task existed
