Only fsck and reinject and the test suite used the Backend, and they can look it up as needed from the Key. This simplifies the code and also speeds it up. There is a small behavior change here. Before, all commands would warn when acting on an annexed file with an unknown backend. Now, only fsck and reinject show that warning.
