Sort Media view not by creation time but by EXIF date

### Steps to reproduce
1. Open "Media" view, wait until photos will be displayed
2. Observe the section headers displaying a month and compare the date the photos have been taken

### Expected behaviour
The photos are displayed regarding the month they have been taken. As the section headers are sorted descendently, the photos inside the section should be sorted descendently, too.

### Actual behaviour
The photos are displayed in totally mixed sections. Old photos in current month, and alike.
It seems that the photos are sorted somehow by "file modification date", not by "EXIF date taken".
