Cleanup bugfix relating to use of a default schema declared in orm.xml: 

- Removed prepending of schema name in PersistenceMappingDefaults.getTableName
  methods as unnecessary.
- Moved storage of default schema name to ClassMappingInfo as that's the only
  place we use it for now.
- Moved setting of default schema name into the more efficient endClassMapping
  method of XMLPersistenceMappingParser.
- Fixed MappingInfo.createTable logic to pass the full table name to 
  SchemaGroup.findTable.  This is important b/c the DynamicSchemaGroup (used
  during the mappingtool's buildSchema action, the default for JPA) dynamically
  adds the table to itself during the findTable operation.  Without the full
  table name it would always add the table to the default schema.
