Merge branch 'restore-get_id' into 'master'

Restore get_id in ExtractsPath

fixes #21334

`Addressable::URI.normalize_component()` around `get_id` which was introduced by 68cea38e and removed in !5878 is still intentionally omitted. Using `normalize_component()` instead of `unescape()` left `%` as is but still broke e.g. spaces (which were replaced by `%20`).
