0.129 won't open empty folders

[Matthias Johnson <penguin@research.att.com>]

Greetings,

I've noticed that 0.129 doesn't like opening empty folders.  I have a
number of inboxes that are fed via procmail.  Sometimes on startup
they are empty and then nnimap just stops dead in its tracks with

Group {name of folder} is not uid-valid.

This also happens if all groups have something in them at startup and
I delete all messages from on of my groups and then do a '1 g'.

Does nnimap have to error out after this.  0.128 works just dandy.
