DDC-700: Proxy class is created for MappedSuperclass class

[doctrinebot]

Jira issue originally created by user gedrox:

When having abstract class as Mapped Superclass the proxy class is created without the "abstract" keyword which raises fatal PHP error "Class %proxyClassName% contains 1 abstract method and must therefore be declared abstract or implement the remaining methods" when read.

I think there is no need to generate the proxy classes for classes marked as @MappedSuperclass at all.

Comment created by gedrox:
