Typing for aliases of @Property methods

- When a property method is aliased to another label, mypy considers the
  type of the alias to be a callable instead of the return type of the
  method; therefore, mypy is likely to error when using them
- This resolves the issue for client.application, client.authorization,
  and Torrent.is_paused
- Instances of the issue (mostly in client.app) arising from camelCase
  aliases will not be resolved; use the snake case names as a workaround
