Update mappings for Elasticsearch 6.2. Update logger

* Update the indexes mappings to be compatible with the newer
  Elasticsearch 6.2.* series.
  Close the index before updating it, and reopen it after to help with
  the re-indexing of the data.

* Update the error logger to include the exception that was thrown.
