Tested and fixed a couple of issues with the disappearingMessages job
Added a simple dependency system for jobs (primarily for the AttachmentUploadJob, but will likely be others later)
Setup the AttachmentUploadJob again (looks like there are cases which use it)
Prevented a possible infinite job deferral loop from causing the app to crash (the loop is still technically possible but the app will continue to run now)
Updated the interactions unique constraints based on testing and discussions around how the serverHash works
Deleted the legacy ReadReceipt handling (now managed via the 'interaction.wasRead' flag and 'SendReadReceiptsJob')
Deleted the unused SSKIncrementingIdFinder
Disabled the attachments and voice message buttons for the first message
Disabled the Disappearing Messages flag for the until the conversation is approved
Fixed a bug where the recipient of a message request could incorrectly get the 'pending approval' state
Refactored some standard auto layout code to use the custom extension code
