Silence the item model tests

Introduce a logging category for the qDebug()-output.

Add a meta type registration for QList<QPersistentModelIndex>, fixing
numerous warnings like:
WARN  : tst_QItemModel::remove(QStandardItemModel:invalid start, valid count 5) QSignalSpy: Unable to handle parameter 'parents' of type 'QList<QPersistentModelIndex>' of method 'layoutChanged', use qRegisterMetaType to register it.

Fix a Clang warning about potential misuse of operator ,
