Subject: Filter enabled folders using a krecursivefilterproxymodel

The KRecursiveFilterProxyModel is necessary until Qt 5.10 when
QSortFilterProxyModel will support recursive filtering.
For the recursive filtering to work we need to make all data available,
so we trigger fetchMore on all added indexes.
