Cannot connect to any server

Something changed on the QT side, and now the client cannot connect to any relay:

$[130] 19:42      ~     > qweechat
Traceback (most recent call last):
  File "/usr/lib/python2.7/site-packages/qweechat/qweechat.py", line 276, in connect_weechat

    self.statusChanged.emit(self.status_connecting, None)
TypeError: Network.statusChanged[str, str].emit(): argument 2 has unexpected type 'NoneType'
Traceback (most recent call last):

TypeError: Network.statusChanged[str, str].emit(): argument 2 has unexpected type 'NoneType'

Looks like QT now forces the use of a string

The issue is also present at line 112 and 143 of network.py
Replacing None by "" seems to fix the issue
