Subject: Fix `AM::Errors.added?` trying to generate a message:
- When a ActiveRecord record get saved and validated as part of a
collection association, the errors attribute are changed to reflect
the children names. You end up with an error attribute that will
look like this:
`author.errors # {:'books.title' => [:blank]}`
https://github.com/rails/rails/blob/2fe20cb55c76e6e50ec3a4ec5b03bbb65adba290/activerecord/lib/active_record/autosave_association.rb#L331-L340
We then can't check if the `books.title` errors was added using
`ActiveModel::Errors#added?` because it tries to generate a message
to make the match and end up calling the "books.title" method
on the Author.
```
author.errors.added?(:'books.title', :blank) => NoMethodError: undefined method `books.title'
```
This patch modify the behaviour of `strict_match?` to not generate
a message to make the comparison but instead make a strict
comparison with the `options` from the error.
