rollback safety number retrusting job

Context

the job to automatically retrust all safety numbers for all publishers and subscribers every 24 hours causes signald to fall over with roughly a few hundred publishers/subscribers.

the bug is tricky enough i want to push off figuring it out until the weekend. in the meantime, eliminate the call to schedule the retrusting job on startup to prevent signald falling over.

Symptoms

After a job runs, signald generates a bunch of nullpointer exceptions that look like this:
