Fixes lingering interactions after removing thread (#1297)

Most of the work was done in SignalServiceKit 0.0.7, this adapts to those changes. Migration to clean any orphaned interactions/attachments. - don't set new migration version until migration was successful. - remove dead code from migrations - rename message.attachments->message.attachmentIds - Remove unused parameter from GroupModel - formatting touched method/'s signatures //FREEBIE
