Commit fdfec2c07a seqmap: refactor seqmap to use slice instead of map
introduced a regression to imap sorting (if supported). The slice passed
to seqmap was being sorted in place by UID, thus breaking any sort order
sent by the server.
Create a copy of the slice to retain the sort order reported to the UI
while also keeping a correct map for seqnum -> UID in the worker.
