Fix 'git show' on signed tag of signed tag of commit

The cmd_show loop resolves tags by showing them, then pointing the
object to the 'tagged' member. However, this object is not fully
initialized; it only contains the SHA1. (This resulted in a segfault
if there were two levels of tags.) We apply parse_object to get a
full object.

Noticed by Kalle Olavi Niemitalo on IRC.
