Don't show preference related menus in the translate infobar in incognito mode.
Don't show preference related menus in the translate infobar in incognito mode.

BUG=51214
TEST=Navigate in a non incognito window to www.google.de. The translate infobar should show. The options menu should have options to always/never translate german.
     Navigate again to that page but from an incognito window, the options menu in the translate infobar should not have any preference (always/never translate) related items.
