Describe the bug
The output of the CommandLineApp DomainGraphExtractor creates different node ID types than running WriteGraph directly through spark shell. They should be the same.

To Reproduce
The following command line command (both DF and RDD):

bin/spark-submit --class io.archivesunleashed.app.CommandLineAppRunner /Users/ianmilligan1/dropbox/git/aut/target/aut-0.50.1-SNAPSHOT-fatjar.jar --extractor DomainGraphExtractor --input /users/ianmilligan1/dropbox/git/aut-resources/sample-data/*.gz --output /users/ianmilligan1/desktop/domaingraph-gexf --output-format GEXF --partition 1

creates an output file that looks like:

<node id="2343ec78a04c6ea9d80806345d31fd78" label="facebook.com" />
<node id="9cce24c55aee4eb39845fde935cca3da" label="web.net" />
<node id="5399465c5b23df17b16c2377e865a0b2" label="PetitionOnline.com" />
<node id="1fbfb6126d36fd25c16de2b0142700d8" label="traduku.net" />
<node id="d1063af181fe606e55ed93dd5b867169" label="en.wikipedia.org" />
<node id="0412791bbc450bbeb5b7d35eaed7e4f2" label="calendarix.com" />
<node id="fb1c73ca981330da55c56e07be521842" label="goodsforgreens.myshopify.com" />

Conversely, if we run this script as per aut-docs:

import io.archivesunleashed._
import io.archivesunleashed.app._
import io.archivesunleashed.matchbox._

val links = RecordLoader.loadArchives("/users/ianmilligan1/dropbox/git/aut-resources/sample-data/*.gz", sc)
  .keepValidPages()
  .map(r => (r.getCrawlDate, ExtractLinksRDD(r.getUrl, r.getContentString)))
  .flatMap(r => r._2.map(f => (r._1,
                               ExtractDomainRDD(f._1).replaceAll("^\\s*www\\.", ""),
                               ExtractDomainRDD(f._2).replaceAll("^\\s*www\\.", ""))))
  .filter(r => r._2 != "" && r._3 != "")
  .countItems()
  .filter(r => r._2 > 5)

WriteGraph(links, "/users/ianmilligan1/desktop/script-gexf.gexf")

We get an output that looks like:

<node id="76" label="liberalpartyofcanada-mb.ca" />
<node id="80" label="lpco.ca" />
<node id="84" label="snapdesign.ca" />
<node id="88" label="PetitionOnline.com" />
<node id="92" label="egale.ca" />
<node id="96" label="liberal.nf.net" />
<node id="100" label="policyalternatives.ca" />
<node id="1" label="collectionscanada.ca" />

Expected behavior
The output of DomainGraphExtractor is preferable to the WriteGraph output. In other words, the nodes as hashes is superior to the notes as ID #s.
