Fixed problem where reserveNow did not work

[SweOlle]

because ocpp server did not recognize a connector as a charger as previous commits changed the name from chargerID to connectorID. Belongs to issue #211

Describe your changes

Changed name from charger to connector in switch statement in server_ocpp because it was not changed when renaming the variable chargerID to connectorID. This caused issues because a variable was taken from the name "chargerID" but was now taken from "connectorID" which resulted in it being "connector" whilst it was waiting for "charger"
