rowsAboutToBeMoved() and rowsMoved() signals aren't emitted for
QSortFilterProxyModel, which meant the two connections in the
ObservingObject's constructor didn't trigger the slots, which let the
test pass (the store/checkPersistentFailureCount stayed at 0).
- Instead connect to layoutAboutToBeChanged() and layoutChanged()
respectively, these two are emitted for QSFPM
- Use PMF syntax
- Verify m_persistent{Proxy,Source}Indexes aren't empty
