Undefined and useless property called in edit forum post link generation

[francescolaffi]

tiny harmless defect, but it still deserves to be solved

bp-forums-templatetags.php:960

[...] wp_nonce_url( bp_get_the_topic_permalink() . $topic_template->post->id . 'edit/post/' . $topic_template->post->post_id . '/' . $query_vars, 'bp_forums_edit_post' ) [...]

the $topic_template->post->id in the link is undefined and does nothing except generating a notice, actually if it was defined the link would be invalid, I guess it's only a copy/paste inattention.

diff is for b1.2, same problem in the trunk but the line is 927 instead of 960
