*Description*:
Currently textbooks for a course are not loaded in i-frame. Reason is that browser cannot find the resources required to load the viewer. In file /lms/templates/pdf_viewer.html, all static urls e.g.
```
${static.url('/static/js/vendor/pdfjs/locale/locale.properties')}
```
have unnecessary /static in the beginning of paths, due to which, the viewer is not loaded correctly and textbooks are not displayed correctly.

So I have removed those unnecessary `/static`(s) from the source paths.
