Popovers must close when rotating screen

[Ugo Riboni]

After rotating the device a few times while an overflow menu is open, the menu will be placed in the wrong position on the screen. The number of rotations before this happens appears to be quite random, but it will eventually happen.

Below is a minimal example that should trigger the bug by rotating the device after opening the overflow menu:

import QtQuick 2.0
import Ubuntu.Components 1.1

MainView {
    id: mainView
    applicationName: "com.ubuntu.developer.ken-vandine.hub-importer"
    automaticOrientation: true
    useDeprecatedToolbar: false

    width: units.gu(100)
    height: units.gu(75)

    Page {
        title: "Test"

        head.actions: [
            Action { name: "Item 1" },
            Action { name: "Item 2" },
            Action { name: "Item 3" },
            Action { name: "Item 4" }
        ]
    }
}

Discussed this with Giorgio, and all Popovers (including header overflow panels, but NOT including dialogs) must close when screen is rotated.

Marked webbrowser-app also affected, because it uses a custom header, and its overflow menu currently isn’t implemented using a popover, so it won’t benefit from the UITK fix.
