unsubscribe() successful, but the callback unsubscribed_info.was_error is true

[petten]

I moved up to release 1.5, although had to change all the callbacks. That came to pass, and all seems well except this:

When calling unsubscribe(), the lockable logger I passed to wampcc was able to log:

LOG 20171110-19:22:53.081567 14684 INFO unsubscribed, subscription_id 28, request_id 3 ...

But upon examining the callback arg struct unsubscribed_info, I found its was_error member was set to true.

I'm sure the previous wampcc version that I had used for a long time had its was_error member set to the right value, though the struct had a different name.

Yep ... I'm able to reproduce. Seems like bug. Will fix soon.

fixed on master branch, commit fcb79e5

Another minor thing - my compiler (GCC 5.4) made a little noise about this:

... include/wampcc/wamp_session.h:94:28: warning: missing initializer for member 'wampcc::auth_provider::user_secret' [-Wmissing-field-initializers] nullptr, nullptr };

It can be made to go away by one's adding one more , nullptr before }; at the end.

Fix confirmed

added your suggestion to resolve compiler warning.
