Update readyForTesting var even on Oobe.initialize() failure.

|readyForTesting| was introduced to let callers know whether
the DOM loading is done so testing APIs accessing DOM can be
successfully called.
Although, in some cases Oobe.initialize() is failed, so
it timed out.
Instead, this CL sets the value always. Then, callers can be notified
even on failure cases, so they can avoid timeout.
