Fixes static config map still being populated after system settings disabled.

Previously, if system proxy was enabled, darwinProxyConf.Static.Protocols got populated with the proxy configuration. If afterwards the system configuration was removed there was no place in the code where the map got reset, which led to incorrect configurations being returned even after calling ReloadConf()
