Remove legacy PY2 sys.argv unicode handling

Fixed crash when sys.stdout was None

When using pythonw on windows, sys.stdout and stdin are None. We had a
legacy unicode_argv handler that was crashing in this instance. Just
removed that, since sys.argv is always unicode on python 3 to fix the
crash.

Closes: https://github.com/deluge-torrent/deluge/pull/361
