Bug DMaaP adapter

The unit test testReceiveAndPostDataFromDmaapNonBuffering has an inherent timing problem. 

The test sends "[\"DmaapResponse11\", \"DmaapResponse22\"]") to the DMaaP adapter and expects two sent messages, first  DmaapResponse11 and then DmaapResponse22.  

At times these might be sent in the other order (first 22, then 11).  

That has to do with some paralellization. Either the unitteest should be fixed so it accepts any order or the paralellization should be fixed.

The easiest  is to fix the unittest.
