a11y_indicator_menu missing icon in High Contrast mode

[Mitsuya Shibata]

Ubiquity greeter mode turn on High Contrast mode via a11y_indicator_menu.
casper-a11y-enable script set up icon-theme to "HighContrast".
However HighContrast doesn't have "accessibility-directory" icon and not
inherit Humanity theme. Therefore unvisible a11y_indicator_menu in High Contrast mode.

Procedure:
1. Bootup from Ubuntu Desktop CD
2. Do nothing in gfxboot (to boot ubiquity with greeter option)
3. Displayed daialog to ask "Try Ubuntu" or "Install"
4. Displayed a11y indicator(blue circle) in top-right
5. Select "High Contrast" in a11y indicator
6. Exec casper-a11y-enable and turn on High Contrast mode

Expected result:
- Stay visible a11y indicator icon

Actually result:
- Unvisible a11y indicator icon, but can select by cursor key

Still happening for alpha 2, additionally the menu doesn't allow you to toggle properly and becomes bugged after you turn it on and then off again.
