Fix bpython-curses bug when passed an argument

Greg Burek · sebastinas · commit 4e3673cc9034 · 2018-09-27T19:52:59.000+02:00
Currently, running `bpython-curses -i file.py` results in:

```
...
  File ".local/share/virtualenvs/flask-ex-03Wix3mp/lib/python3.6/site-packages/bpython/cli.py", line 1905, in main_curses
    bpython.args.exec_code(interpreter, args)
NameError: name 'bpython' is not defined
```

This PR addresses this error by correctly importing args and using it,
like the curtsies implementation.
