fix IE11 error from sentry

What does this MR do?

remove unsupported IE11 URL() constructor

Are there points in the code the reviewer needs to double check?

• there are a few other new URLs in PDF stuff, should they be fixed as well?
• should we lint for this? Couldn't find an existing one so might need modified http://eslint.org/docs/rules/no-new-wrappers
