Bug description: When checking a child entry on a node, it only
checked the first position, which was normally "deleted" if there
were no more children. But in some cases, a tombstoned child was
placed there. If it occurred, even though there were no live child
any more, _entryrdn_delete_key returned "has children" and the delete
operation failed.

Fix description: This patch checks all the children of the to-be-
deleted node and if there is no child or all of them are tombstones,
it goes to the next process. Also, the fixed a typo reported by
chatfield (Thank you!!)
