fix: update link to fragment for same url

[hirasso]

Description

Besides a warning if the URL of a fragment targeted by a a[data-swup-link-to-fragment] would already match the current url, that URL was also not being applied to the link. I see no reason why it shouldn't do so anyways. I currently have a more complex project where I needed this.
