fix for grails-plugins/grails-database-migration#157

[zyro23]

when constructing the sessionFactory bean name for a secondary dataSource, just append the suffix, not the complete dataSource bean name (i.e. sessionFactory_another instead of sessionFactory_dataSource_another)

@zyro23 Could you please verify if this is still an issue with 4.0.0-RC1? and change the PR against 4.0.x branch?

Thanks!
