Fix search limit config item (cross-seed#479)

The SQL query for the filterTimestamps function was malformed and would
return the same (too high, low) timestamp every time, since it didn't
filter for torrent name, and because max and min were reversed. It would
never filter any torrent unless every single torrent had an extant entry
in the db for every indexer.

Fixes cross-seed#453
