gpg: print unknown key IDs in their entirety

Shortening the key is nice in theory but it results in ambiguity which can
be exploited.  Therefore, when encountering an unknown key ID we should
print the whole ID returned by gpg.  This may or may not be the whole key,
however it will match the user preference set in gpg configuration.

Furthermore, the key ID shortening had a couple of issues:

(1) it truncated the key ID (dropping the last digit and outputting only 15
    hex digits) making it very hard to find the correct key on a key server

(2) since only 15 digits were fed into shortkey(), it always emitted the
    ui.debug() warning
