class StubPDO

A stub of \PDO for testing purposes.

We override the constructor method so that PHPUnit can mock the \PDO class. \PDO itself can't be mocked, so we have to create a subclass. This subclass is being used to unit test Connection, so we don't need a functional database but we do need a mock \PDO object.
