With self referential associations, the scope for the the top level should not affect fetching of associations, for example
when doing

Person.male.find :all, :include => :friends

we should load all of the friends for each male, not just the male friends.

Add a repair_helper to repair changes to the validations inside validations_test.rb [#674 state:resolved]

Many of the tests in validations_test would add a new validation to
models.  However, only Topic was being reset with a fairly aggressive
clearing of all validations.  None of the other models being used however
were recieving the same treatment.  Now we use repair_validations(Topic)
for the whole test case because most test cases use Topic and then the
block form of repair_validations(<other_models>) inside any tests that use
other models.
