Bug 1098168 - BaseIcon

Not sure on a CDMA device whether we get a data change event when making a call. If not, we should call to this function when call changes. (on CDMA devices either data call or voice call can be established at the same time)

The other case is similar. When wifi is connected, the text should be set to empty. After confirmed with Jessica, in this case gecko should dispatch the data change event. Now the case is failed after applying the patch so there might be a gecko bug here, please confirm.
