Interfaces passed in initial_introspection are not registered in devices-by-interface

[rbino]

We should copy DataUpdaterPlant.DataUpdater.Queries.register_device_with_interface/4 in Astarte Pairing and add them when initial_introspection is passed during device registration

[eddbbt]

update: This issue was (is) about a corner case misbehavior, such as:

• a device is created with an introspection
• then the same device connects to astarte without declaring an introspection (due to above, this is a valid and legit design choice)
• after that, the interface(s) can be deleted without warnings/errors

it should not be allowed to delete an interface after at least one device that uses the interface(s) performs the initial connection (device state changes from "never connected"), as this could cause service interruptions
