Started trying to add the unit tests that were in the settings refactor branch (need to be refactored due to the implementation changes)
Fixed a bug where the typing indicators wouldn't get cleaned up in some cases
Fixed a bug where returning from the background on the conversation screen would result in the input view being hidden
Refactored the PhotoCollectionPickerViewController to use the SettingsTableViewController convention
Updated the SettingsTableViewModel to worked based on Combine instead of the DatabaseObservable so it's more reusable for non-db cases
Fixed a bug where the scroll to bottom button wasn't working
Fixed an issue where searching was running on the main thread (which could cause UI issues)
Updated the searching to interrupt the previous query when the search term changes
Updated the in-conversation settings to be use the new config-based approach (deleted the OWSConversationSettingsViewController)
Removed an unused notification
Refactored the PrivacySettingsViewController
Refactored the ScreenLock code to Swift
Fixed an issue where the match dark/light setting wasn't getting applied on launch
Update the modal styling for the various settings modals
Updated the MessageRequestViewModel to have the same page size as the HomeViewModel
Fixed a couple minor UI discrepancies
Refactored the old app settings child screens to be configuration based and all in Swift
