hook_og_membership_delete does not have a $type parameter

Problem/Motivation

There appears to be a typo in commons_trusted_contacts.module line 476:

function commons_trusted_contacts_og_membership_delete(OgMembership $og_membership, $type) {

$type is not a valid parameter for hook_og_membership_delete() in OG API.

Proposed resolution

Remove $type, it is not referenced inside the function.

function commons_trusted_contacts_og_membership_delete(OgMembership $og_membership) {
  if ($og_membership->type != 'trusted_contacts' || $og_membership->group_type != 'user') {
    // Not a Trusted-Contact membership type.
    return;
  }

  if (!og_is_member('user', $og_membership->etid, 'user', $og_membership->gid)) {
    // Prevent recursion.
    return;
  }

  // Delete the "opposite" OG membership too.
  og_ungroup('user', $og_membership->etid, 'user', $og_membership->gid);
}
