[OMEMO] Show fingerprint of other devices

[cweiske]

The "Mange devices" list only shows device IDs and no fingerprints.

Neither Conversations nor Dino show their device ID - only their fingerprint.
So it is currently impossible to verify the other devices and remove invalid ones.

BTW, Gajim shows devices IDs.

And have in mind that in according to XEP only devices IDs are guaranteed to be known:
https://xmpp.org/extensions/xep-0384.html#usecases-announcing

And unfortunately any client from users in my contact list does not send label info about device, because this is only recommended attribute... =(

Example from XEP looked so promising...

<device id='31415' label='Conversations on Pixel 3' />

Time to update the XEP!
