Fix for query string parsing in handleEventsEndpoint

[Linch1]

Hello, at line

https://github.com/AsamK/signal-cli/blob/e11e0930209e330649af182eaa0317d2d987d4e8/src/main/java/org/asamk/signal/http/HttpServerHandler.java#L159C13-L160C110

we can see that the getQuery and the Utils.getQueryMap that is used in the next line conflicts, causing the account that are sent, in the query string, for filtering purpose to never be found from the getManagerFromQuery.

signal-cli/src/main/java/org/asamk/signal/http/HttpServerHandler.java

Line 162 in e11e093

List<Manager> managers = getManagerFromQuery(query);

both the formats ?account=+335544777 and ?account=%2B335544777 results after being parsed to someting like

{account: " 335544777"} that starts with a blank space, so an account that starts with a blank space instead that + symbol.

fix: use getRawQuery instead than of getQuery in line 159.

minial example:

import java.net.URI;
import java.net.URLDecoder;
import java.nio.charset.StandardCharsets;
import java.util.HashMap;
import java.util.Map;

public class ServerSimulation {

    public static void main(String[] args) {
        // Simula una URI di esempio con query parameters
        String uriString = "http://localhost:8080/resource?account=%2B3434523423";
        URI uri = URI.create(uriString);

        // Estrae i query parameters
        String queryString = uri.getQuery();
        Map<String, String> query = queryString == null ? Map.of() : getQueryMap(queryString);

        // Stampa i risultati
        System.out.println("Query Parameters:");
        query.forEach((key, value) -> System.out.println(key + " = " + value));
    }

    
    public static Map<String, String> getQueryMap(String query) {
        var params = query.split("&");
        var map = new HashMap<String, String>();
        for (var param : params) {
            final var paramParts = param.split("=");
            var name = URLDecoder.decode(paramParts[0], StandardCharsets.UTF_8);
            var value = paramParts.length == 1 ? null : URLDecoder.decode(paramParts[1], StandardCharsets.UTF_8);
            map.put(name, value);
        }
        return map;
    }
}

just compile it and run it javac ServerSimulation.java and java ServerSimulation :)
Thanks for the great library.

Thanks for the hint!

Btw in recent java version you can run it with just java ServerSimulation.java ;)
