PlacesItemModel: remove redundant set of properties

Summary:
The text, icon and url properties are already set in
`PlacesItem::setBookmark()`, so there is no need to set them here.

The `OnlyInApp` property is part of the KBookmark object that we are
going to set to the place item, so there is no need to set it here either.

Test Plan:
- Open both dolphin and the Plasma file dialog in some app
- Edit the text, url, icon and the "Only show when using this application" checkbox in some place item from the file dialog
- Check whether the place in dolphin keeps getting updated accordingly
