[TIMOB-18869] iOS: "Invalid JSON in where parameter"

When using 4.0.0.RC2 and making an ACS objects query, I get an error where there previously was not one:

[ERROR] :  400: Invalid JSON in where parameter: 745: unexpected token at '%7B%22title%22%3A%22TIMOBAlloy--0Simulator8.3medium1307681024.png%22%7D'

*Steps to reproduce issue* 1. Create a project and include a query for an ACS Object 2. Run the project *Actual Results*: The above error is thrown *Expected Results*: No error is thrown *Notes*: This is the query I am using:

Cloud.Photos.query({
    limit: 1,
    where: { 'title': file.name }
}, function (e) {
    if (e.success) {
        alert("Image found");
    } else {
        alert("Unable to find image");
    }
});
