Place bookmark blue buttons hard to see in night mode

[nicolas-raoul]

Steps to reproduce:

1. Go to Setting, enable night mode
2. Go to Nearby, bookmark a place
3. Go to Bookmarks, select Places tab, tap the place
4. The blue buttons (bookmark/camera/gallery/directions/...) are hard to see

A slightly lighter blue would be better I think. Especially the directions and ... somehow.

Screen-shots:

Same in Nearby map.
