Fix result_from_string for empty return values
An empty string returned from a libnitrokey function can either indicate an error or be a valid return value. Previously, we assumed that it indicates an error. But instead, we should check the last command status and use it to decide whether to return the empty string or an error code. This breaks the unit tests that assume that empty strings cause errors. These will be fixed in the next patches.
