Fix 2575588 - After creating new folder shortcut unable to navigate between home screen using touch.

Somebody fixed a bug in managed dialogs where it wouldn't
create the dialog after a configuration change.  This means that we
shouldn't set mWaitingForResult in createDialog, we need to set it in
onShow.  This is what the add dialog was already doing.
