Fix create sensor failure after process restart

When the virtual-sensor process is intentionally restarted, the
createVirtualSensors method will only create sensors with Type equal
to ModifiedMedian, so if other types of sensors (eg: Sum, Minimum,
Maximum, etc.) are configured in EM.json, they will not be loaded.

This commit will remove the `Type` and create the sensor by
traversing the calculationIfaces when parsing to 'Config: D-Bus'.
