fix(file)!: dont handle case where existing file URL was re-attached in get_full_path

[sagarvora]

The problem described in #17250 will only get solved for new attachments. It will continue for existing attachments.

That's okay, because get_url can be unreliable:

• doesn't give you all domains
• doesn't work if site URL was changed
• works better only when called as part of a request

Same backport labels as #17250 have been added.
