The problem was that clicking on the delete icon was displaying an alert box, prompting the user to confirm whether they actually wanted to delete the element or not, that protractor didn't expect and was causing the following error:
UnexpectedAlertOpenError: unexpected alert open

After searching in Google for a while, we found a solution:
