Swagger: Inconsistency between service .bal file and .bal file created back from yaml

[ChinthakaSenanayaka]

Description:
Create swagger yaml from service bal file. Then created services bal file from that swagger file are not equal.

Steps to reproduce:
hellow_world_service.bal

import ballerina/http;
import ballerina/log;

// By default, Ballerina exposes a service via HTTP/1.1.
service hello on new http:Listener(9091) {

    // Invoke all resources with arguments of server connector and request.
    resource function sayHello(http:Caller caller, http:Request req) {
        http:Response res = new;
        // Use a util method to set a string payload.
        res.setPayload("Hello, World!");

        // Send the response back to the caller.

        var result = caller->respond(res);
        if (result is error) {
            log:printError("Error sending response", err = result);
        }
    }
}

Created swagger file:
hello_world_service.swagger.yaml

openapi: 3.0.1
info:
  title: hello
  version: 1.0.0
servers:
- url: /hello
paths:
  /sayHello: {}
components: {}

bal file created from the swagger yaml (hello.bal):

import ballerina/http;
import ballerina/log;
import ballerina/mime;
import ballerina/swagger;

listener http:Listener ep0 = new(9090);

@swagger:ServiceInfo {
    title: "hello",
    serviceVersion: "1.0.0"
}
@http:ServiceConfig {
    basePath: "/"
}
service hello on ep0 {
    resource function sayHello (http:Caller outboundEp, http:Request _sayHelloReq) {
        http:Response _sayHelloRes = new;
        string _sayHelloPayload = "Sample sayHello Response";
        _sayHelloRes.setTextPayload(_sayHelloPayload);
        _ = outboundEp->respond(_sayHelloRes);
    }

}

hellow_world_service.bal service is at GET http://0.0.0.0:9090/hello/sayHello
hello.bal service is at GET http://0.0.0.0:9090/sayHello
