title: Orientjs - Issue with update remove
body: <p>I am sorry if this has been asked before but I did a quick search and did not found something.
  I am having a problem with a query similar to "update #48:1 remove tags[0]", where "tags" is an Embedded list. When I ran the command in the console it works just fine but when I use db.query("update #48:1 remove tags[0]"); in node it does nothing.
  I was wondering if there is an issue with the brackets because if I choose to remove the whole list, db.query("update #48:1 remove tags");, it works fine. I tried escaping the brackets but still no luck. Tried the code both with Orient2.2 and Orient3.</p>
