Mute query errors on routine builds

[bmschmidt]

There's a slew of failed queries on builds, as noted here:

23/2016 15:30:09:ERROR:Query failed: 
SELECT count(*) FROM wordsheap
23/2016 15:30:09:ERROR:Query failed: 
SELECT count(*) FROM titleLookup
23/2016 15:30:09:ERROR:Query failed: 
SELECT count(*) FROM authorLookup
23/2016 15:30:09:ERROR:Query failed: 
SELECT count(*) FROM fedNumberLookup
23/2016 15:30:09:ERROR:Query failed: 
SELECT count(*) FROM paragraphNumberLookup

The code is happily recovering from there--they happen because certain tables aren't yet built, which it then proceeds to build. So nothing should be written to the screen.
