[MV3] Toggling redirect per website does not work

[lidel]

Found while reviewing https://github.com/ipfs/ipfs-companion/pull/1182

Old behavior

Clicking on the toggle does two things

• adds a redirect exception which disables redirect for the specific Origin
• reloads the page from original URL

(and toggling it back re-enables redirect for that origin and reloads page so it loads from local gateway again)

Bug in MV3

Clicking does nothing – local URL is still in address bar, and opening website again still redirects.
