Show special message on "Clear completed" when no tasks can be completed

[spacecowboy]

on Clear completed maybe you can add a counter and add a different message when there are no completed tasks to be deleted

As of now, when deleting completed notes, it simply shows "deleted". If no notes were deleted, it shows nothing. Simply add a message that says "Did not delete any notes" when requesting a delete with 0 completed notes
