Refactor edit message arch #80
Description
The current arch of editing a message is to create a new message that is linked to the old message through the archivedMessage key. This is overly complex and could be much simpler by just having text be a MAP rather than a register and then we can append a new value in when a message is edited rather than making a whole new message.
AC:
- Refactor iOS, Android and Web
- Refactor the text of the message to contain an MAP of text rather than just a string.
- The map should contain a created date and the text. This is so that we can use the createdDate to find the latest text entry and use that one for display
