More fixes for public.oils_tsearch2

First, we don't want to fully exclude records which don't have a
metabib.record_attr_vector_list entry, so we do a LEFT JOIN instead
for that table.  Otherwise, some records error out when ingesting
(see placeholder record -1 in the stock data set).

Second, let's add a check for 'active' which appears to have been
always missing.
