psusensor: fix sensor name matching during rescan

When psusensor is created, sensor name is modified using
boost::replace_all_copy(sensorName, " ", "_").
Apply the same call when matching up sensor name string in base config
and name of the sensor object.

Without this change, psusensor service does not create sensor object if
pmbus configuration has spaces in Name field, like
{
...
"Name" : "PSU$BUS $ADDRESS"
...
}

Tested:
psu sensor name with space are created correctly with the change.
