set-url: entering url without http(s):// prefix no longer works v3.11.3

[fictitiousexistence]

Describe the bug
Typing fqdn in set-url (github.com / google.com/etc) without http(s):// prefix no longer takes you to the direct url, instead shows search results.

Issue occurs in Nyxt 3.11.3. Works properly in ≤3.11.2

Precise recipe to reproduce the issue

1. Run set url command (o in vi mode)
2. type github.com > enter
3. Takes you to search results instead of https://github.com

[André A. Gomes]

Thanks for the bug report @fictitiousexistence.

The regression was introduced in #3344. A deep refactor of set-url is required.
