Added an error state to the OpenGroupSuggestionGrid
Fixed a bug where the settings button wouldn't appear for the sender of a message request once approved
Stopped configuration messages from automatically creating threads for sync'ed contacts (now they will only be created if there are messages)
Updated the ConfigurationMessage to stop truncating the list of contacts but filter the full set (also update the logic to include previously approved contacts)
Fixed the unread message counting for message requests
Updated the message request banner to indicate the number of message requests with an unread message
Updated the message request banner to automatically disappear if the user has no unread message requests
Renamed a variable for ReadReceipt management to make it a bit more self-documenting (it looked like it would trigger a read receipt to be sent regardless of the setting)
Removed the 'presentTimer' logic from the 'ModalActivityIndicatorViewController' (the delay looked buggy, if it does have "blipping" issues then we can fix those separately)
Removed the "Back" text from the back buttons
Removed the inset on the 'Path' settings button so the text remains horizontally centered
Hid the settings button from message request threads
Fixed an issue where the back button would remain visible in a conversation when the search field was visible
Fixed an issue where the tintColor of the conversation search field didn't match the global search field
Fixed an issue where sending an attachment response to a message request wouldn't approve the message request
Updated the size and positioning of the message request 'Clear All' button to match the DM 'Next' button
Updated the message request 'Clear All' button to start visible (so it's visible during the push animation) since that's the most likely state it'll be in
Updated the 'Message Requests' cell to use the pinned background colour
Updated the fallback for contact thread names to be a middle-truncated string (4 characters either side)
Fixed a bug where the ConfigurationMessage was getting generated before the contact state was persisted to the database in the message request flow causing odd behaviours (now generating the ConfigurationMessage within the same transaction)
Fixed a bug where sending a message to an existing message request thread once the message requests item has been hidden would show the message requests notification and trigger the section to re-appear on the home screen
Fixed a bug where blocked contacts weren't getting excluded from the contacts list in the configuration message
