test: explicitly "add" file before some commit in test-rollback.t

`hg commit -A` will revert the `hg addremove` step if the commit fails. However
`hg rollback` currently does not.

We are about to improve internal consistency around transaction and dirstate and the behavior of `hg rollback` will align on the other behavior in the process.

Before doing so, we make sure the test is using a separate call to `hg add` to
avoid the test scenario to be affected by that future change.

note: the behavior change for `hg rollback` seems fine as it affect a niche
usecase and `hg rollback` usage have been strongly discouraged for a while.

Define helpers.

  $ hg_log () { hg log -G -T "{rev}:{node|short}"; }
  $ commit () { echo "foo - ${2:-$1}" > $1; hg commit -Aqm "Edited $1"; }
  $ strip() { hg --config extensions.strip= strip -q -r "$1" ; }

Setup hg repo.

  $ hg init repo
  $ cd repo
  $ touch x; hg add x; hg commit -m "initial"
  $ hg clone -q . ../clone
  $ commit a

  $ cd ../clone

  $ commit b

  $ hg pull -q ../repo

  $ strip '1:'

The branchmap cache is not adjusted on strip.
Now mentions a changelog entry that has been stripped.

  $ commit c

Not adjusted on commit, either.

On pull we end up with the same tip, and so wrongly reuse the invalid cache and crash.

  $ hg pull ../repo 2>&1 | grep 'ValueError:'
  ValueError: node a3498d6e39376d2456425dd8c692367bdbf00fa2 does not exist (known-bad-output !)
