gamepad: Check that the DocumentLoader is not null

Gamepad timestamps are reported relative to the navigationStart timestamp, accessed from the DocumentLoader's DocumentLoadTiming. In some scenarios the document may have been detached before the NavigatorGamepad is initialized, causing the DocumentLoader to be nullptr. This CL checks that the DocumentLoader is non-null, and uses the current time in place of navigationStart if it is null.
