sysuptime always return 0 when SNMP and MIB task are started in classic startup mode

All new firmware using SNMP is using the new startup mode calling MIBDatabase_Task_Init() and SNMPServer_Task_Init().
However SNMP component still offers the old way to start it using static task list.
Using this way SNMP tasks are started but the MIB-2 entry "sysUpTime" will always return 0 instead of the real uptime of the device.
