package test requirements

[MatthewPikar]

I fixed a bug which made delete crash when requested entities do not exist. Specifically I added a test to see if store.list returns any elements before heel is called.:

if(elements.length === 0) return cb(null, null);

store.list(args, function(err, elements) {
    if(elements.length === 0) return cb(null, null);
    var redisArgs = _.pluck(elements, 'id');

    redisArgs.unshift(table);

    dbConn.hdel(redisArgs, function(err, result) {
        if (!error(args, err, cb)) {
            cb(null, [result]);
        }
    });
});

I was about to make a pull request, but then I noticed that the test script is expecting seneca.test.store.shared and I don't want to submit anything without running the tests first. Where does that come from and how should I add it? Are there other dependencies I need to fulfill?
