hs: Set rendezvous circuit timestamp_dirty all the time

We used to check if it was set to 0 which is what unused circuit have but when
the rendezvous circuit was cannibalized, the timestamp_dirty is not 0 but we
still need to reset it so we can actually use it without having the chance of
expiring the next second (or very soon).

Fixes #23123
