TBA: Delete Orbot Providers
Orbot (and OrbotService specifically) implement three Android app Providers:
These are used by Orbot's onion service subsystem where the user can run a service from their device or store an auth cookie associated with an onion service.
We do not need these at this moment and we don't have plans for exposing a UI for these, and the existance of these prevents installing multiple versions of TBA (using different package names) because the Provider names collide. We can safely delete these from the service's manifest and TorService class.
