Reverse order of branch names

[sheremetyev]

When submitting multiple PRs from Sapling CLI, branches on GitHub are created in reverse order.

Example: submitted three PRs and got:

• https://github.com/sheremetyev/sapling-test-1/pull/1 has branch name "pr3"
• https://github.com/sheremetyev/sapling-test-1/pull/3 has branch name "pr1"

---

Steps to reproduce:

1. create a new repository on GitHub

2. clone repository

$ sl clone https://github.com/sheremetyev/sapling-test-1.git
$ cd sapling-test-1

3. create several commits

$ echo foo > foo.txt ; sl add foo.txt ; sl ci -m 'adding foo'
$ echo bar > bar.txt ; sl add bar.txt ; sl ci -m 'adding bar'
$ echo baz > baz.txt ; sl add baz.txt ; sl ci -m 'adding baz'

4. submit multiple PRs at once

$ sl pr

5. check names of branches in the created PRs on GitHub

Expected: branch names suffixes match PR numbers Actual: bottommost PRs in the stack has lowest PR number but highest branch number
