title: jhipster doesn't generate liquibase changelog for generated entities
body: <p>I did the following:</p>
  
  <ul>
  <li>Created new jhipster application following the <a href="http://jhipster.github.io/creating_an_app.html" rel="nofollow">development guide</a></li>
  <li>Launched the Application class with hot-reload VM options as per <a href="http://jhipster.github.io/development.html" rel="nofollow">here</a> from IntelliJ; command line <code>C:\dev\jdk1.8.0\bin\java -javaagent:spring_loaded/springloaded-jhipster.jar -noverify -Dspringloaded=plugins=io.github.jhipster.loaded.instrument.JHipsterLoadtimeInstrumentationPlugin -Didea.launcher.port=7538 "-Didea.launcher.bin.path=C:\dev\IntelliJ IDEA\bin" -Dfile.encoding=UTF-8 -classpath "*snip very long classpath" com.intellij.rt.execution.application.AppMain com.mysoftware.Application</code></li>
  <li>Created new entity using <code>yo jhipster:entity project</code> as per <a href="http://jhipster.github.io/creating_an_entity.html" rel="nofollow">here</a></li>
  <li>Expected results - everything works</li>
  <li>Obtained results - going to <code>http://localhost:8080/#/project</code> gets <code>org.h2.jdbc.JdbcSQLException: Table "T_PROJECT" not found</code></li>
  <li><code>/src/main/resources/config/liquibase/changelog</code> has only <code>db-changelog-001.xml</code></li>
  <li>Restart didn't help</li>
  </ul>
  
  <p>So it seems like the step </p>
  
  <pre><code> If you have used hot reload in the previous step, JHipster has automatically created a new file named src/main/resources/config/liquibase/changelog/db-changelog--002.xml.
  </code></pre>
  
  <p>from <a href="http://jhipster.github.io/creating_an_entity.html" rel="nofollow">here</a> hasn't really taken place.</p>
  
  <p>What am I doing wrong?</p>
  
  <p>What's the easiest way to manually invoke the generation of the db-changelog-002.xml; as I'm not keen in writing it manually, the entity class already has all the information.</p>
