fix: ensure the all items selected message is always shown when applicable

state.options contains the source list, selectedItems contains all
selected items which might also be present in state.options.
Looking at the 2 lists lenghts does not work because selectedItems can
of course have other data items besides the options added from the
source list.
The fix is to check that all state.options id are found in selecteItems.
