Comment:

 I further debugged this. It seems to be related to my use of the vanguards
 script, and not related to #25552 fortunately.

 Basically, it seems like `service->state.next_rotation_time` was getting
 reset very often, because the vanguards script was HUPing Tor and hence
 keep calling `move_hs_state()` which does not update `next_rotation_time`.

 I think the fix here is to patch `move_hs_state()` to update
 `next_rotation_time`.
