Sharing link doesn't get updated in some cases

[ryanwitt]

Hi!

Wanted to report a minor bug I've found in whichloadsfaster.

Steps to reproduce:

1. Enter site URLs A&B for comparison, compare.
   1.1. Note the resulting comparison sharing link.
2. Change A URL to some C URL, left B unattended, compare.
3. Note the sharing link for C&B comparison.

Actual result:
Link still contains A&B URLs.

Expected result:
Link should reflect all URL changes, so it should contain C&A for second comparison.

Hope this helps!
