Avoid adding a column for the discriminator if the column is already defined.

Use case:
The User entity has a ManyToOne relationship to the UserType entity.
The ManyToOne relationship is done using the column user_type_id.

I want to use this column user_type_id for the discriminator map.

Everything works except the doctrine:shema:update.

An exception is raised: The column is already defined.
The solution: For the discriminator column, do not try to add the column if this one has already been set.
