[FIX] fetch..folder: make manual attach work again

In the past manual attachment was limited to the model defined in the
folder, by overriding the selection for the object in a fields_view_get
method. This no longer works as the method is not called any more. Setting
the selection to just this model through other methods also does not work,
neither setting a default model on a Reference field.

So basically now attaching a mail to any object is allowed.
