Checking receiver certificates may cause a NPE

[Roman Vottner]

On looking at the code that handles the sender certificate check I noticed that if a check for valid participantId, docTypeId or processId in _getReceiverEndpoint(...) fails null is returned that leads to execution of the respective null-check block, which performs operations on the previously tested objects, which may be null at this point,and therefore throw a NPE.
