Fix errors getting duplicated when passed validations options:

- In 86620cc3aa8e2630bc8d934b1a86453276b9eee9, a change was made
  on how we remove error duplication on a record for autosave
  association

  This fix has one caveat where validation having a `if` / `unless`
  options passed as a proc would be considered different.
  Example:

  ```ruby
  class Book < ApplicationRecord
    has_one :author

    validates :title, presence: true, if -> { true }
    validates :title, presence: true, if -> { true }
  end

  Book.new.valid? # false
  Book.errors.full_messages # ["title can't be blank", "title can't be blank"]
  ```

  While this example might sound strange, I think it's better to
  ignore `AM::Validations` options (if, unless ...) when making the
  comparison.
