Auto-configuration of Spring Integration's JDBC support does not use the auto-configured DataSource

With Boot 2.0.4:

   IntegrationAutoConfiguration.IntegrationJdbcConfiguration:
      Did not match:
         - @ConditionalOnSingleCandidate (types: javax.sql.DataSource; SearchStrategy: all) did not find any beans (OnBeanCondition)
      Matched:
         - @ConditionalOnClass found required class 'org.springframework.integration.jdbc.store.JdbcMessageStore'; @ConditionalOnMissingClass did not find unwanted class (OnClassCondition)

Clearly we have a DataSource but auto config doesn't find it for some reason.

Thanks for the report. The auto-configurations aren't properly ordered.
