Fix `no active span when trying to log` tracing error on startup.
Example error:
```log
synapse.logging.opentracing - 427 - ERROR - wake_destinations_needing_catchup-0 - There was no active span when trying to log. Did you forget to start one or did a context slip?

### Why did this happen before?
This previously occurred because we called `init_tracer(...)` after the
reactor started up in `_base.start()`. But we actually attempt some
database transactions earlier than that which try to do some tracing
because of that `oidc = hs.get_oidc_handler()` line.
Notice `oidc = hs.get_oidc_handler()` happened before `_base.start(hs)`:
5be7679dd9/synapse/app/homeserver.py (L397-L408)
With this PR, I've updated things to `init_tracer(...)` earlier on
alongside where we `setup_logging(...)`.
