Versionable does not work with column alias on primary keys [+patch]

Using the Versionable behavior on a model which has a column with an alias and which is also primary causes the generation of a wrong version of the versionable table.

Example:

 
ModelFoo:
  model_id as id
  username
  password

Generates tables:
model_foo (model_id, username, password, version)
model_foo_version (id, model_id, userrname, password, version)

It should be:
model_foo (model_id, username, password, version)
model_foo_version (model_id, userrname, password, version)
