hg-fast-export.py: don't step on previous --hg-hash notes

If exporting in incremental mode it's important to preserve
any preexisting refs/notes/hg value which is easily accomplished
by adding a reset + from combination.

Ideally the previous refs/notes/hg value should be stored in the
heads cache and warned about changes outside the import process
just like all the other heads, but that's something for another time.
