[kcm/kwinrules] Fix first item position on property list
The first time the list in Add properties
is shown, the position of the first
delegate is miscalculated as (0, 0) and gets hidden behind the section header.
(https://bugs.kde.org/show_bug.cgi?id=422289)
It only re-positions when the delegate is destroyed and re-created, for example, when setting and deleting a filter text.
This delays the overlayModel
filtering until the list is first shown, which makes
the delegate position correctly.
