Ben Boeckel acfe53c588 cmListCommand: make list(ACTION not_a_list) succeed when idempotent

The operations changed here all are no-ops on empty lists anyways, so
just have them succeed when given non-extant lists.

  - `list(REMOVE_ITEM)`
  - `list(REMOVE_DUPLICATES)`
  - `list(SORT)`
  - `list(FILTER)`
  - `list(REVERSE)`

 better-empty-list-behavior
 --------------------------
 * The :command:`list` operations ``REMOVE_ITEM``, ``REMOVE_DUPLICATES``,
   ``SORT``, ``REVERSE``, and ``FILTER`` all now accept a non-existent variable
   as the list since these operations on empty lists is also the empty list.
