[PATCH 14/14] index-pack: silently assume missing objects are promisor

[Jeff Hostetler <git@jeffhostetler.com>]

From: Jeff Hostetler <jeffhost@microsoft.com>

Teach index-pack to not complain about missing objects
when the --promisor flag is given.  The assumption is that
index-pack is currently building the idx and promisor data
and the is_promisor_object() query would fail anyway.
