regression error with options in 0.8-3

Hi,

The most recent commit (2fd4f65) with version 0.8-3 introduced a regression error.

Specifically, my code (run api, run.lua) does

local q = require 'lusty-store.query'()
...
local count = store.options(q)

After upgrading fro 0.8-2 to 0.8-3, the count is now always the entire set of records. (it ignores the options). I tested this with a queries that included either q[field].eq or q.field[is]

I tracked this down to the specific line in colmt.lua

-      query = next(query) and query or nil
+      query = query and next(query) or nil

Reverting just this line made the options work properly

Note -- reverting causes other problems. I added a pull request which fixes this plus keeps other tests passing.
