controllers: don’t pass start=0 to BaseRepository.get_changesets()

MercurialRepository.get_changesets() can fail if passing start=0 if the
revision 0 is not in self.revisions. That can happen if revision 0 is not in
the visible subset of the revisions in the repository. Before Kallithea
changeset 7c43e15fb8bc7a73f17f577e59a4698589b6809d, it was working by chance
because start=0 was treated like start=None in the relevant places
(GitRepository.get_changesets still does that).

The intention of passing start=0 was seemingly to not limit the start.
Therefore passing start=None (or nothing, as it’s the default value) should be
correct.

I got the following traceback before this change:

Traceback (most recent call last):
