Add Preserve UTM params to redirect interaction

Currently, if you land on a page say:

abc.myshopify.com/pages/page1?utm_source=facebook

And then on that page there is some redirect to some other part of your store, the utm_source param (or any other UTM params) will be stripped. It would be nice to preserve these to ensure tracking works.

This is especially salient for cross domain funnels where the UTMs are important in cross domain tracking.
