Don't include iconOverlays
in rolesData if it is empty
If this role isn't in the model yet, it would be `QVariant::Invalid` which is obviously a distinct type from an empty string list. This means `KFileItemModel::setData` treats them non-equal and potentially does expensive operations on the model, which is called every time a role is resolved in `KFileItemModelRolesUpdater`. With this change, the number of pointless layout calculations is significantly reduced.
