Long poll broken in 0.13

[herm]

Trying to connect to my server via long poll return error 500 after the upgrade to 0.13.0. It worked in an earlier version (0.11?).

Output from Crossbar:

Unhandled Error

Could be related to #610

I'm still getting the same issue running current git master (701a2d2).

Right. Thanks for reporting (again) =(

Obviously, all the resources like WampLongPollResourceSessionSend etc need a logger .. easy enough.

@herm does this fix your issue? (You can try before merge by pip install https://github.com/meejah/crossbar/archive/issue702-loggers.zip#egg=crossbar)

[herm]

Yes, the problem is gone now. Thanks.
