Add checks in the core so that unsaved objects are not used in queries.

[Nicklas Nordborg]

This will generate a Hibernate exception similar to:

 net.sf.basedb.core.BaseException: object references an unsaved ransient
 instance - save the transient instance before flushing: net.sf.basedb.core.data.AnnotationSetData
 at net.sf.basedb.core.HibernateUtil.loadData(HibernateUtil.java:1131)
 at
 net.sf.basedb.core.AnnotationSet.findAnnotation(AnnotationSet.java:335)

 net.sf.basedb.plugins.Tab2MageExporter.getExperimentalFactorValues(Tab2M
 ageExporter.java:766)

 net.sf.basedb.core.PluginExecutionRequest.invoke(PluginExecutionRequest.
 java:88)
 at
 net.sf.basedb.core.InternalJobQueue$JobRunner.run(InternalJobQueue.java:

The AnnotationSet.findAnnotation() is just one such method that needs a check. There are lots and lots of other places...
