Patches for ov3 and makehistory

[Richard Todd]

Fixing a couple of bugs:
1) Bogus error message in makehistory
2) Problem in tradindexed_add that showed up when rebuilding overview from
scratch and you had recently done some rmgroups -- the removed group is gone
from active (and hence from the new group.index), but there are still articles
in spool with Xref:s in the removed group.  tradindexed_add attempts to
write to the overview for the removed group, fails, and reports an error. 
This patch makes tradindexed_add ignore the error and continue with the other
groups the article is crossposted to if the group is no longer in group.index.
