App Coexistence offsets are not calculated correctly

When setting the AppCoexistence offsets as follows:

curl -i -H "Content-Type: application/json" -H "Cache-Control: no-cache" --data '{ "sfc-of-renderer-config" : { "sfc-of-table-offset" : 20, "sfc-of-app-egress-table-offset" : 80 }}' -X PUT --user admin:admin http://localhost:8181/restconf/config/sfc-of-renderer:sfc-of-renderer-config

Which would set SFC to start writing flows in table 20, SFC actually starts writing flows in table 22.

This is because it wasnt compensating for the Classifier Table (which is not used in app coexistence) and the TrasportIngress Table (which is now table 0 with app coexistence).
