Description of problem:

In Satellite 6.3, a updateinfo.xml like this will work

====
<updates>
  <update from="--------------@phoenixspa.it" status="stable" type="security" version="1-25">
    <id>FCSA:2017-0001</id>
    <title>Security Update for fc-proftpd-chroot</title>
    <release>PROFTPD-CHROOT</release>
====

However, this doesn't work in 6.4 as pulp is expecting the version to be a number.


Version-Release number of selected component (if applicable):

6.4
How reproducible:

Easy


Steps to Reproduce:

sync a custom repo with the updatexml.info as above


Actual results:

The sync fails with errors:

Expected results:

The repo sync should work.
Additional info:

I believe this is a regression.
