Check in user_relationship_limits_user_limit() grants unlimited relationships

I'm using 6.x-1.0, but the bug is in the dev version as well.

In this function:

function user_relationship_limits_user_limit($rtid, $user) {
  //default to no restrictions if we don't find anything
  $user_limit = 0;
  //Go through each role of the user, find the max allowed limit
  foreach ($user->roles as $key => $value) {
    //Find role limit and add it to our array
    $user_role_limit = user_relationship_limits_role_limit($rtid, $key);
    //if there's no value for any role, no restrictions and there's nothing else to check below
    if (empty($user_role_limit)) {
      return;
    }
    //keep resetting this value to the highest value we've found
    $user_limit = max($user_limit, $user_role_limit);
  }
  return $user_limit;
}

This check screws everything up:

    //if there's no value for any role, no restrictions and there's nothing else to check below
    if (empty($user_role_limit)) {
      return;
    }

I have a relationship type that authenticated users aren't allowed to create. I have a VIP role and I've set a limit of 1 relationship for that role. When that foreach goes through each role it begins with the authenticated role and checks for a role limit on that role, but there isn't one and the function returns nothing thus granting everyone unlimited relationships of that type.

I'm not sure what that check is supposed to do, but just removing it makes everything work as it should.
