Separate common interfaces from client-specific classes

Changes:
- Move client-specific classes to client/src/models
- Extract common interface to standalone files in common/interfaces
- Remove unused features from client-specific classes
    - These are features which were once used on the old server, but are now no longer needed
    - Remove getObject() method for Account, Contact, and Conversation
    - Remove lookups, registrationState and registeringName from Account
    - Remove resolving logic from Contact
    - Remove requests and listeners from Conversation (once used for Socket.IO and promises on server)
- Rename services/Conversation.ts to services/conversationQueries.ts
- Update imports

Future work:
- Create interface versions of Account, Contact, and Conversation
- Create new interfaces to replace Records on server
