deployer: get('branch') returns incorrect branch when run within a locally run task

Describe the bug If you have set a branch within a stage by using ->set('branch', 'develop'), the branch is ignored completely for tasks set to run locally.

To reproduce

1. Copy the contents of deploy.php below.
2. Run dep deploy staging.

Actual behavior ➤ Executing task branch:name Branch develop ➤ Executing task branch:localname Branch master

Expected behavior ➤ Executing task branch:name Branch develop ➤ Executing task branch:localname Branch develop

Environment

• Deployer version: v6.8.0
• PHP version: v7.3.20
• Deployment target(s) OS: CentOS 7

Content of deploy.php

<?php
namespace Deployer;

require 'recipe/common.php';

set('allow_anonymous_stats', false);

set('branch', 'master'); // Default branch

host('staging')
    ->set('branch', 'develop')
    ->set('deploy_path', '/var/www/html');

task('branch:name', function() {
    writeln('Branch ' . get('branch'));
});

task('branch:localname', function() {
    writeln('Branch ' . get('branch'));
})->local();

desc('Deploy your branch bug report.');
task('deploy', [
    'branch:name',
    'branch:localname'
]);
