hs-v2: Copy needed information between service on prunning



Turns out that when reloading a tor configured with hidden service(s), we
weren't copying all the needed information between the old service object to
the new one.

For instance, the desc_is_dirty timestamp wasn't which could lead to the
service uploading its descriptor much later than it would need to.

The replaycache wasn't also moved over and some intro point information as
well.

Fixes #23790

o Minor bugfixes (hidden service v2):
- When reloading tor (HUP) configured with hidden service(s), some
information weren't copy to the new service object. One problem with this
was that tor would wait at least the RendPostPeriod time before uploading
the descriptor if the reload happened before the descriptor needed to be
published. Fixes bug 23790; bugfix on 0.2.1.9-alpha.
