Fix 'queryStringParameters' when the url contains multiple question marks

[marcomontalbano]

This fix is related to the issue #54.

Given a request that looks something like this:

?url=https://www.youtube.com/watch?v=0uwe_PhCRcY&filter[0][field]=title&filter[0][value]=TestElement

The value of event.queryStringParameters should be an object like this:

{
    "url" : "https://www.youtube.com/watch?v=0uwe_PhCRcY",
    "filter[0][field]" : "title",
    "filter[0][value]" : "TestElement"
}

Instead of the following object:

{
    "url": "https://m.youtube.com/watch"
}
