These exact same tests were in both 'direct_dispatch', and in
'bfv_dd_types'. Oddly, one SELECT was missing from 'bfv_dd_types', though.
Add the missing SELECT there, and remove all these type tests from
'direct_dispatch'.

Now that there are no duplicate table names in these tests, also run
'direct_dispatch' in the same parallel group as the rest of the direct
dispatch tests. That's a more logical grouping.
