Subject: [PATCH] Don't crash if you get one of these "{}" entries that
 1Password makes.

It looks like some version of 1Password has obsolete entries that still have
JSON files listed, but the entirety of the JSON is "{}" ... we now check if we
got an empty table back from the Lua JSON parser and treat it as a dead entry.
