function rabbit_hole_uninstall() - error

Came accross this error when I uninstalled Rabbit Hole 6.x-1.1

fatal error - call to non-existent function node_type_get_types() on line 48 of rabbit_hole.install (not exact wording but you get the gist)

line 48:
$node_types = array_keys(node_type_get_types());

node_type_get_types() is from Drupal 7 so needs replacing with node_get_types()

So line 48 should be:
$node_types = array_keys(node_get_types());

Rabbit Hole uninstalled without error after I made this change
