Fix bug causing crash if localStorage not available

[victorquinn]

Greetings,

I'm doing some server-side rendering and was getting this error when trying to build my app:

      if( localStorage[query_key] ){
          ^
ReferenceError: localStorage is not defined

It only started recently as this version (0.8.3) didn't make it to npm until 16 days ago. Now my whole app crashes on build. Going back to 0.8.2 explicitly fixes the build as it takes me back in time before that commit was applied.

This PR should fix that issue and prevent crashes when running server-side.

Thanks for the fix, @victorquinn! Really appreciate it. I'm going to release this as soon as possible.

Fix available here but you can update with npm as always!

Thanks again for the fix.
