[Transaction] Remove @ORM\Entity

[alexandre-abrioux]

Following Doctrine's documentation (http://docs.doctrine-project.org/en/latest/reference/inheritance-mapping.html)

a mapped superclass cannot be an entity

otherwise extending the class leads to errors such as described here : http://stackoverflow.com/questions/21536634/doctrine-query-crashing
There is hence an architecture choice to be made : either keep the @ORM\MappedSuperclass annotation or remove it.
I personally think this is the bundle's user responsibility to extend the class should he need to persist the object, this is why I removed the @ORM\Entity annotation.
