`PdoSessionHandler` class assumes that the PDO object is set to throw exceptions, not errors. I added a line in the constructor to set that attribute, so configuration/query errors are able to be seen and caught a lot easier.

        route: licenses_projects
        ignoreAttributes: [path]
    requirements:

```

Ensures that ``path`` isnt added as a GET parameter in case the ``licenses_projects`` doesnt have a path in the pattern.
