maildir: always sort by at least uid
Commit 29205fdd07c0 ("maildir/search: get MessageInfos in parallel") introduced parallel searching of maildir backends, which improves search and filtering performance. When no filter is specified, the search algorithm is still used with no criteria because the FilterCriteria field always contains "filter" as a minimum. With the new parallelized search, the message order becomes random. Only use the search algorithm if there is a filter specified. If a filter *is* specified and a sort order is *not*, the messages will go through the search algorithm and become randomized, but not sorted back in order. Always default to a UID order sort (the same as prior to this commit) when no sort order is specified.
