title: remove Default in migration?
body: <p>In the migration I alter <code>enabled</code> field to set to 1 value as default.</p>
  
  <pre><code>public function up()
  {
      Schema::table('client', function (Blueprint $table) {
          $table-&gt;boolean('enabled')-&gt;default(1)-&gt;change();
      });
  }
  </code></pre>
  
  <p>In <code>down()</code> method - How do I remove <code>default()</code> ? I know can do <code>default(0)</code> but default was never created during create table. </p>
