Laravel 5.4 changes that break the debugbar

[martindilling]

I stumbled into a few issues trying to get this working with the 5.4-dev (I know it's not released yet, but if I don't write them now, I wouldn't write them xD).
I don't really have time to work on a PR, but hopefully this can at least help find the right places to look :)

This commit broke the log listener:
laravel/framework@57c82d0?diff=split
What I could figure out was that this needs to accept the new MessageLogged class instead of the separate values:

This commit broke the session collector:
laravel/framework@66976ba?diff=split
I see the interface/class is typehinted here:
https://github.com/barryvdh/laravel-debugbar/blob/master/src/DataCollector/SessionCollector.php
https://github.com/barryvdh/laravel-debugbar/blob/master/src/SymfonyHttpDriver.php#L51

Hope it can save at least a little bit of hunting around :)

#583
Don't know if it's good or not, but at least the application starts up in both 5.3 and 5.4 :)
