Feature request: allow to refetch content on URL modification

[nicofrand]

Is your feature request related to a problem? Please describe.
When I update a bookmark's URL (if it expired or was moved to another URL, without redirection), the title and snapshot is not updated.

Describe the solution you'd like

I'd like the title and snapshot to be fetched again from the new URL and used in the bookmarks list.

Describe alternatives you've considered

Manually updating the title. For the snapshot I haven't found a way yet.
