We need to apply url upgrading when loading profiles for comparison

Here is a STR:

1. open [this profile](https://profiler.firefox.com/compare/calltree/?globalTrackOrder=0-1-2&implementation=js&localTrackOrderByPid=17686%20from%20profile%201-0~17686%20from%20profile%202-0~&profiles[]=https%3A%2F%2Fdeploy-preview-2039--perf-html.netlify.com%2Fpublic%2Fa48e69780e84edab57dd2a029bd8b6b34ba0419b%2Fcalltree%2F%3FglobalTrackOrder%3D0-1-2-3%26hiddenGlobalTracks%3D0-1-2%26hiddenLocalTracksByPid%3D17686-0%26implementation%3Djs%26localTrackOrderByPid%3D17606-1-0~17686-0~%26range%3D5.3162_35.9437%26thread%3D4%26transforms%3Df-js-Fs%26v%3D3&profiles[]=https%3A%2F%2Fdeploy-preview-2039--perf-html.netlify.com%2Fpublic%2Fa48e69780e84edab57dd2a029bd8b6b34ba0419b%2Fcalltree%2F%3FglobalTrackOrder%3D0-1-2-3%26hiddenGlobalTracks%3D0-1-2%26hiddenLocalTracksByPid%3D17686-0%26implementation%3Djs%26localTrackOrderByPid%3D17606-1-0~17686-0~%26range%3D5.3162_35.9437%26thread%3D4%26transforms%3Df-js-Fs%26v%3D3&thread=0&transforms=f-js-Fs&v=4). This comes from doing a comparison with [this profile](https://profiler.firefox.com/public/a48e69780e84edab57dd2a029bd8b6b34ba0419b/calltree/?globalTrackOrder=0-1-2-3&hiddenGlobalTracks=0-1-2&hiddenLocalTracksByPid=17686-0&implementation=js&localTrackOrderByPid=17606-1-0~17686-0~&range=5.3162_35.9437&thread=4&transforms=f-js-Fs&v=3) specified twice.

=> obviously, the "focus on subtree" doesn't work in the comparison view, but works fine when loading the profile normally.
