SessionHandlerTest::testClientAuthMD5WithoutNonce3(),

[tests] Fix MockSyncItem key assignment

Detected by CommandHandlerTest::testSyncAdd(),
CommandHandlerTest.cpp:286

The test case has most probably started failing when ec17dfc introduced
calling newItem->setKey() inside StorageHandler::addItem().  Anyway,
according to the documentation of StoragePlugin::addItems(), the
implementation was wrong since the initial commit. Also see 7b8c432
(removing the aLocalKey argument -- probably wrong conflict resolution)
and c4ce210 (adding aLocalKey again).
