Async void should not be used.

The http appender seems to work fine from my console application but when running an owin web api, I get the following error

[InvalidOperationException: An asynchronous module or handler completed while an asynchronous operation was still pending.] The following stack post explains the reason why.

I update the code to use ContinuesWith. I tested the fix in my existing code and seems to work.

This should also resolve https://github.com/jjchiw/gelf4net/issues/50

Hmm, that failure does not seem to be related to the code I changed.
