* Do not offer to mark statuses as sensitive if there is no undeleted status with media attachments
* Fix crash when marking statuses as sensitive while some statuses are deleted
Fixes#21910
* Fix multiple strikes being created for a single report when selecting “Mark as sensitive”
* Add tests
* Fix Sidekiq warnings about JSON serialization
This occurs on every symbol argument we pass, and every symbol key in hashes,
because Sidekiq expects strings instead.
See https://github.com/mperham/sidekiq/pull/5071
We do not need to change how workers parse their arguments because this has
not changed and we were already converting to symbols adequately or using
`with_indifferent_access`.
* Set Sidekiq to raise on unsafe arguments in test mode
In order to more easily catch issues that would produce warnings in production
code.
