notmuch-tag: don't sort messages before applying tag changes

Browse source 
It's not neccessary to sort the results before we apply tags. Xapian
contributor Olly Betts says that savings might be bigger with a cold
file cache and (as unsorted implies really sorted by document id) a better
cache locality when applying tags to messages.
