The wh_upsert_credential_group function was incorrectly attempting to
update the session connection fact table. There are a couple problems
with this:
1. At the time that this runs, there would be no session connection facts
for this session.
2. This function is meant to update the session fact table, there is a
separate function that associates the credential group with the
session connection facts.
This also fixes another bug that was causing expired rows of the
credential dimension to be included in the group membership. And finally
it fixes a typo in the function name.
