api.sync() silently fails if no token set.

[ijoseph]

Expected behavior

 python -c "from todoist import TodoistAPI; api = TodoistAPI(); api.sync()"

outputs a warning indicating no token has been set.

Actual behavior

Fails silently; api.state is empty.

I fixed this but don't have perms to open a PR.

Behavior after patch:

❯ python -c "from todoist import TodoistAPI; api = TodoistAPI(); api.sync()"

You can just fork it and provide a PR. :)

Just be sure to check the token attribute on TodoistAPI instead of sync_token (which is a different thing).
