[TBC] SpellManager.CastSpellByNameOn("name", "unit") breaks after a while

Hello, I don't edit this function, but server can do (and do it generally), and yes it is possible than he forget to pass all arguments. 

Would it be detectable, if I created a reference to the original function on startup (say, on /reload) and then only called that function directly through Lua (which would be unprotected Lua call)?

If not, that's something I could do. 

Basically like this:
 

EventsLua.AttachEventLua(LuaEventsId.PLAYER_ENTERING_WORLD, context => Lua.LuaDoString(@"
if not _CastSpellSafe then
	_CastSpellSafe = CastSpellByName;
end    
"));
Lua.LuaDoString("if not _CastSpellSafe then ReloadUI() end;");
Lua.LuaDoString($"_CastSpellSafe('Polymorph', 'focus');");

If you can use random name for "_CastSpellSafe" but I don't think that it is detectable.

This fixes it. Weird bug though.
