[BUG] - Sometimes an unexpected identity file path is parsed

[teamwork-alockhart]

Description

The wrong identity file path is parsed. When the wrong identity file path is present, there is a configuration in which the Host parameter is just a wildcard. If there are multiple wildcards, the last one is used when the wrong identity file path is parsed.

Steps to reproduce

Put the following in your ~/.ssh/config file

Host remote_host
  HostName hostname.com
  User user
  IdentityFile ~/.ssh/id_rsa_good

Host *
  AddKeysToAgent yes
  IdentityFile ~/.ssh/id_rsa_bad

Parse the config with the following code:

use ssh2_config::SshConfig;
use std::io::BufReader;

// Parsing ssh config
let config_path = <path to your config>;
let config = std::fs::File::open(config_path).unwrap();
let mut buf_rdr_conf = BufReader::new(config);
let ssh_config = SshConfig::default().parse(&mut buf_rdr_conf).unwrap();

// Get settings from config
let config = ssh_config.query("remote_host");
let host_name = config.host_name.unwrap();
eprintln!("host = {host_name}");
let mut identity_paths = config.identity_file.unwrap();
eprintln!("available identity paths = {identity_paths:#?}");

let identity_path = identity_paths.pop().unwrap();
eprintln!("identity path = {}", identity_path.display());
let user_name = config.user.unwrap();
eprintln!("user = {user_name}");

Note that the program prints other parameters just to be sure that all the others are correct.
Up until now, I've never had an issue with the others, but maybe that's because I don't actually use any other overlapping parameters in the wildcard configuration.

Expected behaviour

Program prints

identity path = ~/.ssh/id_rsa_good

Actual behavior

Program prints

identity path = ~/.ssh/id_rsa_bad
