Fix a bug when reading tuples from config
If the config contains a tuple of integers (for example, if a bind IP address is specified) then strings_to_binary() calls tuple_to_list() followed by strings_to_binary(), which then calls list_to_binary() because the list looks like a string. Then list_to_tuple() is called on the returned binary, causing a crash. This patch corrects the problem by calling strings_to_binary1() instead, which ensures that the value that is passed into list_to_tuple() is a list.
