Return correct date in ActiveModel for time to date conversions

time.to_date conversion happens considering leap years
so a conversion of "Day.new({'day(1i)'=>'1', 'day(2i)'=>'1', 'day(3i)'=>'1'})" results in saving the date as Mon, 03 Jan 0001
which might seem weird on the user level, hence falling back to parsing on string level resolves this data mismatch
Fixes #28521
