C#: Connect only once for each signal of a script

Since the list of signals in `CSharpScript::event_signals` retrieved
from calling `ScriptManagerBridge.UpdateScriptClassInfo` already
includes the signals from base scripts there is no need to iterate the
hierarchy again on `CSharpInstance::connect_event_signals`.
