mq: prevent the creation of a queue whose name is already taken

Each check is moved under the code handling the relevant option, and
a new one is added for --create. This fixes duplicated entries being
added to the queues list.

#!/bin/sh

hg init
touch a
hg add a
hg ci -m "a" -d "1000000 0"

echo 123 > b
hg add b
hg diff --nodates

hg diff --nodates -r tip

echo foo > a
hg diff --nodates

hg diff -r ""
hg diff -r tip -r ""
