FIX: Do not prevent other topic timers running on error (#13665)
There was an issue with the TopicTimerEnqueuer where any timer
that failed to enqueue_typed_job with an error would prevent
all other pending timers after the one that errored from running.

To mitigate this we just capture the error and log it (so we can
still fix it if needed for bug crushing) and proceed with the
rest of the timer enqueues.

The commit https://github.com/discourse/discourse/pull/13544 highlighted
this issue originally in hosted sites.
