DatabaseHelper: Add back ro.telephony.default_network

    Fix ro.telephony.default_network setting parsing

    * The code that parses ro.telephony.default_network is broken,
    instead of reading numbers separate by comma, it reads the first
    number and replicates it for other slots. Settings like "8,1" will
    be written to the db as "8,8"
