Can not changeColumn with TIMESTAMP and limit

• CakePHP Version: 3.6.11.
• Migrations plugin version: 2.0.0.
• Database server: MySQL
• PHP Version: 7.1.13

What you did

Created migration

use Cake\ORM\TableRegistry;
use Migrations\AbstractMigration;

class UpdateTimestamps extends AbstractMigration
{
    public function change() {
        $table = $this->table(TableRegistry::get('Messages')->getTable());
        $table->changeColumn(
            'created_at',
            'timestamp',
            [
                'default' => 'CURRENT_TIMESTAMP(4)',
                'null'    => false,
                'limit'   => 4,
            ]
        );
        $table->update();
    }
}

With Xdebug found that in class PdoAdapter method execute():
vendor/robmorgan/phinx/src/Phinx/Db/Adapter/PdoAdapter.php:167

SQL was:
ALTER TABLE messagesCHANGEcreated_at created_at TIMESTAMP(4) NOT NULL DEFAULT 'CURRENT_TIMESTAMP(4)'

Expected Behavior

Must work ))

Actual Behavior

As result I've got exception:

Exception: SQLSTATE[42000]: Syntax error or access violation: 1067 Invalid default value for 'created_at' in [/var/www/sepagateway/vendor/robmorgan/phinx/src/Phinx/Db/Adapter/PdoAdapter.php, line 167]

Start at vendor/robmorgan/phinx/src/Phinx/Db/Adapter/PdoAdapter.php:167 and trace how changeColumn options produce the shown ALTER TABLE SQL. Reproduce the migration with MySQL and verify that CURRENT_TIMESTAMP(4) is emitted as a valid default rather than an invalid quoted value, while preserving the TIMESTAMP limit and NOT NULL behavior.
