Header and popup menus don't handle rotation correctly

[Sebastien Bacher]

Using rtm-40 on krillin
- click on a photo
- open one of the menu of the headerbar
- rotate the device

the popdown menu gets misplaced, rotating back the device in the previous orientation doesn't bring it back where it was either

that's also an issue with the popup menu on the album view
- create an album
- rotate the screen it landscape
- press the album for some seconds

the menu opens in the wrong direction and over the album image

This is caused by a bug in the SDK: https://bugs.launchpad.net/ubuntu-ui-toolkit/+bug/1375837

We will close the popovers on rotation, see https://bugs.launchpad.net/ubuntu-ui-toolkit/+bug/1375837

Seb128's issue is a separate bug, because there the popover is opened after rotating. Please report a separate bug for that.

unduplicating due to previous comment, the album view has the popup wrong even without rotation after opening
