[v14beta] Wrong type of table object

[MaXyM]

When doing RE from existing database, all tables are set to Type: Table, Stereotype: table
But when using synchronization of existing model with existing database (feature: Show Differences [With Options]), new tables are added with Type: Class, Stereotype: table.
The difference is indicated by different icons in Project Browser (see picture)

It causes the interconnected issues:
1. such added object (Type:Class) is not linked with DatabaseBuilder (DatabaseBuilder menu item is not present in contect menu of the element)
2. it's not possible to select Database type for such object. Instead of Database property, it has Language one
3. Further attempts of synchronization will suggest to add the same table again and again and again creating duplicated objects

Moreover, Type: Table cannot be set manually. Types list doesn't contain Table type. This particular behavior is the same as in v13.5
