Several join records are created when using nested_attributes in HABTM
When creating a new instance using nested attributes, several records in the join table are created.
Attached a test that proves the bug for HasAndBelongsToMany association. The bug has been also detected in has_many :through associations.
Bug was introduced in commit 6b2291f33063b6742cba84f5f64e03de9907c1f8, hence I'm assigning a responsible :-)
