Log Message:
Update ruby-activerecord32 to 3.2.5.

3.2.4 had some regression related problem.

## Rails 3.2.4 (May 31, 2012) ##

*   Perf fix: Don't load the records when doing assoc.delete_all.
    GH #6289. *Jon Leighton*

*   Association preloading shouldn't be affected by the current scoping.
    This could cause infinite recursion and potentially other problems.
    See GH #5667. *Jon Leighton*

*   Datetime attributes are forced to be changed. GH #3965

*   Fix attribute casting. GH #5549

*   Fix #5667. Preloading should ignore scoping.

*   Predicate builder should not recurse for determining where columns.
    Thanks to Ben Murphy for reporting this! CVE-2012-2661
