Monolog BufferHandler does not flush at the end of the request

[dnna]

This handler flushes using a register_shutdown_function, which is never triggered with PPM. We need to find a way to call the flush() function of the handler (and maybe any other Monolog handlers that have it?) at the end of the request.

Interesting finding. Maybe we should look at shutdown functions at the end of each request and invoke all?

I'm not sure if its possible to iterate the shutdown functions in PHP code, I don't think they are exposed (closest I found was https://stackoverflow.com/questions/3140257/list-of-registered-shutdown-functions).

I was thinking of handling it on the framework's bootstrap, but then it will have to be handled for each framework separately.

Should have been fixed by #279
