Title: [1.1] Fix email validation error I18n symbol lookup

And include %{value} for interpolation in validation messages.
If not specifying a custom validation message or symbol this
will now use the same error message as rails' format validator.

This is the proper fix for the issue mentioned in PR #2364.

I'll create a separate PR to fix this in master (which should also apply to 1.2+).
