Don't force imap.host to be set when imap.tunnel is set

The documentation for git-imap-send suggests a tunnel setting such as

  Tunnel = "ssh -q user@server.com /usr/bin/imapd ./Maildir 2> /dev/null"

which works wonderfully and doesn't require a username, password or port
setting.

However, git-imap-send currently requires that the imap.host variable be
set in the config even when it was unused.  This patch changes imap-send
to only require that the imap.host setting is set if imap.tunnel is not
set.  Otherwise, server.host is set to "tunnel" for reporting purposes.
