Fix applying sensor scale on first read

In Sensor::addValue(), the adjustValue() function was being called
before the _scale member was getting set.  So until the first interval
timer expired the sensor value would be unscaled. For example it could
show a temperature of 27000.0 instead of 27.0.

To fix this, reorder the code so that first _scale would get set, then
the sensor value would get adjusted based on _scale, and finally the
value could be set on the Value interface.

Tested:
Use a big INTERVAL config value so that I can check the first read of a
sensor does leave it unscaled.  Then test with fix and check that it
is correct.
