vt730 master: Mis-spelled filename

Load a page in vtiger with the developer console enabled.

I'm seeing http 404 errors:

GET http://dev.libertus.co.uk/vt730/layouts/v7/lib/todc/js/popper.min.js 404 Not found

If you look in that directory the file is actually called popper.min.js.js

So either the filename is wrong (likely), or the code trying to load it.

Looks the problem was created 2 days ago with this commit @uma.s
