 When the posts array doesn't start with the index 0, it generates an error
 due to hard code `0`.

 Before:
 {{{#!php
 <?php
 public function rewind_posts() {
     $this->current_post = -1;
     if ( $this->post_count > 0 ) {
         $this->post = $this->posts[0];
     }
 }
 }}}

 After:
 {{{#!php
 <?php
 public function rewind_posts() {
     $this->current_post = -1;
     if ( $this->post_count > 0 ) {
         $this->post = $this->posts[array_key_first($this->posts)];
     }
 }
 }}}
