Hotfix/jl/query selector all graceful degredation

Older browsers, such as IE8, may not be able to process the passed in selectors to querySelectorAll.  Adding a try/catch block will help with this, and allow the Analytics script to continue processing.

To test:
- Visit your site with all supported browsers and ensure Analytics loads and works.
- For the new ngs-header, there are still some issues that need to be taken care of outside of modules-analytics, but fixing this error is the first step to resolving those issues.
