title: liquibase generateChangeLog command skips tables
body: <p><code>Liquibase</code> <code>generateChangeLog</code> doesn't generate changesets for all the tables in the schema. Out of the 169 tables in the schema I get changesets for only 152. I couldn't find any similar issues posted online. Has anybody else faced a similar issue. What could be causing such a behaviour ? </p>
  
  <p>I am using oracle. Here are a few examples of the table names.</p>
  
  <p>DISPLAY_PROPERTY</p>
  
  <p>EXTERNAL_TRADE</p>
  
  <p>EXTERNAL_TRADE_AUDIT</p>
  
  <p>QUOTE_SPECIFICATION</p>
  
  <p>QUOTE_SPECIFICATION_ACCOUNT</p>
  
  <p>QUOTE_SPECIFICATION_ATTRIBUTE</p>
  
  <p>QUOTE_SPECIFICATION_PRICING</p>
  
  <p>V_SYMBOL</p>
