[py3] Let InstanceCommand.run_arg() always return an int
The caller of this method (which is method "run_args") does `max(status,
self.run_arg(appid))` and run_arg might return None if the underlying
<cmdname>_instance method returns None. On python3 max(1, None) breaks
with "TypeError: unorderable types: int() > NoneType()". So we enforce
run_arg() method to return an integer even if the underlying method
returns None.
This fixes call of "cubicweb-ctl i18ninstance" with Python3.

Patches should be submitted by email at the cubicweb-devel@lists.cubicweb.org
mailing list in order to get reviewed by project integrators or any community
member.
The simplest way of send patches is to use the ``hg email`` command available
through the *patchbomb* extension of Mercurial. Preferably, patches should be
*in the message body* of emails. When submitting a revised version of a patch
series, a prefix indicating the iteration number ``<n>`` of the series should
be added to email subject prefixes; this can be achieved by specifying a
``--flag v<n>`` option to ``hg email`` command.
