2 "from" sql clauses appear in certain hql cases

I used your patch, which generates the following SQL statement on current version:

select catalogent0_.IdCatalogEntry as col_0_0_, catalogent0_.IdCatalogCategory as col_1_0_, catalogent0_.IdProductType as col_2_0_, catalogcat1_.[Name] as col_3_0_, producttyp2_.[Name] as col_4_0_ from CatalogEntriesEntity catalogent0_, CatalogCategoriesEntity catalogcat1_, ProductTypesEntity producttyp2_ where catalogent0_.IdCatalogCategory=catalogcat1_.IdCatalogCategory and catalogent0_.IdProductType=producttyp2_.IdProductType and catalogcat1_.IdProductCatalog=5

Select statement seems right, so I have just added your passing unit test to the source code.
