[PATCH 2/4] pack-objects: do not get distracted by stale refs

[Johannes Schindelin <johannes.schindelin@gmx.de>]

It is quite possible for, say, a remote HEAD to become stale, e.g. when
the default branch was renamed.

We should still be able to pack our objects when such a thing happens;
simply ignore invalid refs (because they cannot matter for the packing
process anyway).
