Fix pressing Refresh button not removing deleted sensors

Issue: when clicking the Refresh button at top right corner of the
WebUI, sensors that were removed from Redfish are not removed from the
WebUI but still shown with old sensor values.
Root cause: current code keeps a list of sensors. Click on Refresh
button just checks and updates sensors returned by Redfish, it does not
check if sensors are still present or not. This is incorrect for
sensors on hot plug devices or PLDM sensors when the sensor source is
not available. In this case, sensors are completely removed instead of
just their values changed to n/a.
Solution: Initialize an empty array sensor state to retrieve
existing sensor data whenever loading sensors.
