Navigation icon is red on night theme on Android Lollipop

[Fs00]

While doing some tests on Lollipop, I've noticed that for some strange reason when the night theme is enabled in settings, the navigation icon in the app bar is red instead of white.

It doesn't seem to be a recent regression, since the bug was present even at commit 4a620a9 (yes, I've randomly checked out a random old commit and gave it a try).

It is also worth noting the missing margin for the dropdown arrow in the top right corner (it's too close to the profile picture, compared to recent Android versions).
