Fix a couple of bugs in imap synching
b/10111339
b/10125810
The first problem was that the imap BEFORE clause
is exclusive, so messages on the date given in
BEFORE will not be sent. Now, on the sync for the
most recent messages, we will just not specify a
BEFORE clause, so we can always get the most recent
messages even if our clock drifts from the server.
The second is that some imap servers do not accept
time information on the query dates, and that causes
errors. The imap spec defines the BEFORE and SINCE
clauses to come with a <date> only, not a time,
and although it seems that at least some imap servers
handle that, it can't be expected to always work.
