Fix un-initialized time owner/mode in manager

The timeOwner/Mode in Manager class has no init value, and it is
initialized with the cached time owner/mode in file system.

In most of time it is OK because there is cached time owner/mode.
But if the BMC does a factory reset, the cached values are cleaned up,
and in next reboot the timeOwner/Mode will not be initialized at all.

The fix is to give default time owner/mode, so when BMC comes from
factory reset it uses default time settings.

Tested: Verify the timeOwner/Mode have correct init values after factory
        reset.
