[Dovecot] UIDL bug

I noticed a problem with handling UIDL msgnumber in test46. If you do "UIDL 1" on a POP3 connection it returns the UID of the message followed by a dot and an error message. I made 2 changes:

I added the following line to line 527 of src/pop3/commands.c

ctx->message = message;

I changed line 559 from:

if (list_uids_iter(client, ctx))

to:

if (!list_uids_iter(client, ctx))

Next time I'll submit an actual diff, I've made lots of other changes and comments in my source though so it's harder.
