[ActivityPub] Caching of Following/Followers interactions and collections
Follow interaction: - Fixed mini-bug where the subscriber profile was being used as the subscribed - Updated cache subscription-related values in both instances - Tested and working with local GS instances Unfollow interaction: - Updated cache subscription-related values in both instances - Tested and working with local GS instances Followers/Following collections: - Now returning ActivityPub profiles only - Stored collections in cache Misc: - Fix bug concerning the retrieval of public/private-key after in-function generation
