Setup SMS filter during activation if legacy mode is used

If the user disabled VVM on pre-O devices then upgrade to O, dialer will not setup the filter because VVM is disabled. The legacy mode which translate VVM SMS into traditional notifications needs the filter to operate. This CL sets up the filter if legacy mode is used.
