tests: fix test-convert-git to work w/ "git pull" requiring strategy

A recent change to git (031e2f7ae195) made it an error to not specify a strategy
(`--rebase`, `--no-rebase`, `--ff-only`), instead of just the warning it was
previously. As far as I can tell, `--no-rebase` is the behavior we were getting
before, and the only one that makes the test work.

# simple script to be used in hooks
#
# put something like this in the repo .hg/hgrc:
#
#     [hooks]
#     changegroup = python "$TESTDIR/printenv.py" <hookname> [exit] [output]
#
#   - <hookname> is a mandatory argument (e.g. "changegroup")
#   - [exit] is the exit code of the hook (default: 0)
#   - [output] is the name of the output file (default: use sys.stdout)
#              the file will be opened in append mode.
