Validation in file.js doesn´t work correctly

This is a bug which happens when validating the file extension on the file input and both cases are related.

The div outside the input file has the same id as the "-upload" input file, then file.js throws an error "this.value" is undefined, as validateExtension is pointing to its parent div, and therefore it hasn't got any value tag.
When a user submits a file using the field, the user removes the uploaded file and tries to upload a wrong extension file, the second validation never happens as the file field attaches twice the validation in $(selector, context).bind('change', {extensions: extensions}, Drupal.file.validateExtension); (removing the text from the previous validation) This may be solved as in https://www.drupal.org/node/2593147#comment-10452571 →

The process to test if everything works as expected is to create a new file upload item with some extensions to validate, once you've choosen the file if the validation works as expected it should show the error:
Drupal.t("The selected file %filename cannot be uploaded. Only files with the following extensions are allowed: %extensions." ....

Try to upload an image with the right extension, hit the remove button, try again to upload an image with the wrong extension, does the validation work again?
