Multilingual sites with path prefix have broken source and licensing JS links

Problem/Motivation

When on a multilingual site that uses path prefixes for language selection, the URL generated to the original file in the source and licensing comment incorrectly includes the path prefix, resulting in a 404.

Example of what is currently output:
/* Source and licensing information for the line(s) below can be found at http://example.com/en/sites/all/modules/custom/my_custom_module/script.js. */

Example of what is expected:
/* Source and licensing information for the line(s) below can be found at http://example.com/sites/all/modules/custom/my_custom_module/script.js. */

Proposed resolution

The code currently uses the url function, when it should use the file_create_url function.
