import from camera doesn't rescan
The Mass Storage Camera "import from camera" feature doesn't rescan the filesystem when removing / re-inserting a memory card.
steps to reproduce:
1) insert + mount memory card
2) press "scan for devices"
3) press "import from camera"
4) select some images
5) unmount + eject card
6) take some more photos
7) re-insert+mount memory card and do steps 2-3
8) images taken in step 6 should be visible
8) list of available photos is the same as step 4
