Masayuki Nakano 4ca52542bb Bug 1504911 - part 5: Make HTMLEditor::InsertTableCellsWithTransaction() create AutoPlaceholderBatch and AutoTopLevelEditSubActionNotifier r=m_kato
Currently, calling nsITableEditor.insertTableCell() does not cause dispatching
"input" event since it does not create AutoPlaceholderBatch.  Additionally,
different from InsertTableRowsWithTransaction() and
InsertTableColumnsWithTransaction(), it does not create
AutoTopLevelEditSubActionNotifier.

Because of those APIs should work similarly, we should make it creates
both auto class instances.
