Add tests for the lock command

This change adds tests for the lock command. For the Nitrokey Pro we
cannot test too much because the only side-effect is that the password
safe is closed and it will be opened automatically again by virtue of
our non-interactive testing methodology.
For Storage devices we verify that the encrypted volume is closed, which
is a documented side-effect.
