Update nitrokey crate to 0.4.0-alpha.3

This change updates the version of the nitrokey crate that we use to
0.4.0-alpha.3. This version is the supposedly last pre-release before
0.4.0, with no further major anticipated changes.
In order to integrate with this new version we have to adjust the way we
connect to a Nitrokey device by funneling those connection requests
through a global manager object. The rationale behind that step being
that the underlying libnitrokey actually cannot handle access of
multiple devices at the same time, and so the manager object is used to
prevent accidental wrong concurrent usage.
Because a device object now effectively keeps a reference to the
manager, we need to provide an additional lifetime to that and derived
objects.
Lastly, the use of a manager is also the reason why the tests had to be
adjusted to no longer accept device objects in their signatures, but
only the respective model for which to invoke the test. That is required
because, as elaborated earlier on, having a device object implies having
taken a reference to a manager (in that case owned by nitrokey-test),
and that reference clashes with the nitrocli code itself attempting to
take the manager. We side step this problem by merely accepting a Model
object, which can be passed around independently of the manager itself,
meaning that nitrokey-test does not need to hold such a reference while
the test is run.
