Incorrect minimongo behavior when using $in and regular expressions

[avital]

Originally reported by @guilhermedecampo.

var coll = new Meteor.Collection("test");
coll.insert({title: "foo"});

// expected: {title: "foo", _id: ...}
// actual: as expected on server, undefined on client
console.log(coll.findOne({$or: [{title: {$in: [/foo/]}}]}));

// expected: {title: "foo", _id: ...}
// actual: as expected on server, undefined on client
console.log(coll.findOne({title: {$in: [/foo/]}}));

// this one works fine
console.log(coll.findOne({title: /foo/}));

Thanks. I'm doing a round of auditing on minimongo now and I'll try to deal with this as I get to $in.
