<formlet> bug - stomps on @_form_this, @_form_field_path, @_form_field_paths_by_object

[jevan]

The formlet tag doesn't preserve @_form_this, @_form_field_path, @_form_field_paths_by_object

So if it is used in the middle of a form, any calls that depend on those attributes that occur after the formlet won't work (e.g. param_name_for_this).

The culprit seems to be the with_form_context call.
