Report command errors properly
So far we have taken all nitrokey::CommandError objects and put them in formatted form into the Error::Error variant. What we really should do, though, is to preserve the original error, with the additional context provided by the caller, and report that up the stack directly. Doing so has at least the benefit that we are able to check for expected errors without hard coding the textual representation as maintained by the nitrokey create. This change refactors the code accordingly and adds two tests for such expected error codes.
