Hopefully this will fix this error:

Rather than relying on (often unreliable) 3rd party keyservers, use
keyring.debian.org for updating the keyring-maint keys - in this
instance we know the keys are already present in the Debian keyring
so this limitation of keyring.d.o is not a problem.

did we managed to get by only chance till now?

Alternatively templates could have used the {% now %} tag, but I'm going
with the smaller change.

John has joined keyring-maint and did most of the last update, so
plumb his details (email → UID mapping, fingerprint) into the keyring
git checking infrastructure.

the code would crash while parsing a `gpg --check-sigs` output with
lines like:

sig:%::22:485E1BD3AE76CB72:1506259130::::[Invalid signature class] :10x::0064BBAEF91E13B2BCF21889485E1BD3AE76CB72:::8:

that, by their nature, would be first, before any uid.

This happened on process 124, causing the following crash in production:

Reorder elements in rt_ticket template

See merge request !4

We put fingerprint and uid first, as that are the most
relevant items for DSA, and probably also for keyring.

Also, rename "Username" to "uid".
