The legal_get_accept() function needs to set $accept[$key] to NULL when it isn't set in the DB object.

The title states what needs to happen. The reason is the returned array needs to contain all of the possible elements so that other items in the code doesn't need to check if the element is set in the array before using it. Issue created without patch to document the issue. If/when I get the time to pull the repository I can create the patch but it is a simple

else {
  $accept[$key] = NULL;
}

in the foreach loop in the function.
