Fix non-keyed test for remove

* Fix non-keyed test for remove. result.removedStoredTr checks any count
  greater than 0. removeStoredTr represents any <tr> node in target
  'table.table'. Removing row two <tr>, index 1, means removedStoredTr
  will be 1 based on target, which results in an invalid error message.
  Now the <tr> node to be removed is ignored.
