allow ManyToMany associations with referenced column name different from 'id'

[awm1]

Subject

I've found out that if I want to audit entity with ID column with name different from 'id' :

class User { /**

• @ORM\Id()
• @ORM\Column(name="user_name",type="string") */ private $userName; /**
• @ORM\ManyToMany(targetEntity="AppBundle\Entity\Department", inversedBy="members", cascade={"persist"})
• @ORM\JoinTable(
• name="systemusers_department_membership",
• joinColumns={@ORM\JoinColumn(name="systemusers_id", referencedColumnName="user_name")},
• inverseJoinColumns={@ORM\JoinColumn(name="department_id", referencedColumnName="id")}
• ) */ private $departmentMembership; }

...those ManyToMany assoc isn't referred by its correct identifier name, but static 'id' string which will throw Exception. So I try to get it from available source, however I'm not sure if this is the right way to obtain it. I am targeting 1.x branch because this is simple fix which should not break anything.
