Improve MessageQueueJobTest: * test that the message actually reaches the outbox, and has all the required attributes -> found and fixed bug where attributes were registered in the MDA instead of outboxinterface -> TEST DOESN'T WORK CURRENTLY because of an uncommited change to AttributeFactory allowing repeated registration of attributes. I will get that reviewed and commited. * disable KWallet -> no longer calls kbuildsycoca -> no longer hangs when run with ctest
