title: Sequence "HIBERNATE_SEQUENCE" not found for h2 test with GenerationType.AUTO
body: <p>I am trying to migrate one of our services to Spring Boot 2.0.3.
  While most of the tests are fine, one of them fails with error:</p>
  
  <pre><code>Caused by: org.h2.jdbc.JdbcSQLException: Sequence "HIBERNATE_SEQUENCE" not found; SQL statement:
  call next value for hibernate_sequence [90036-197]
      at org.h2.message.DbException.getJdbcSQLException(DbException.java:357)
      at org.h2.message.DbException.get(DbException.java:179)
      at org.h2.message.DbException.get(DbException.java:155)
      at org.h2.command.Parser.readSequence(Parser.java:5970)
      at org.h2.command.Parser.readTerm(Parser.java:3131)
      at org.h2.command.Parser.readFactor(Parser.java:2587)
  </code></pre>
  
  <p>This is really confusing because all teh entities rely on the same generation id mechanism:</p>
  
  <pre><code>@GeneratedValue(strategy = GenerationType.AUTO)
  </code></pre>
  
  <p>It's a repository test and the repository itself is very straight-forward:</p>
  
  <pre><code>@Repository
  public interface OrderDetailsRepository extends JpaRepository&lt;OrderDetails, Long&gt; {
  
      OrderDetails findFirstByOrderIdOrderByIdDesc(String orderId);
  }
  </code></pre>
  
  <p>What can possible go wrong here?</p>
  
  <p><strong>PS:</strong> And, yes, there is both <code>orderId</code> and <code>Id</code> field present in the entity.</p>
