viewDestroyed_ should default to true #1942

I think it make more sens to default viewDestroyed_ to true. This avoids methods annotated with @IgnoreWhen(IgnoreWhen.State.VIEW_DESTROYED) to be called before the fragment has been created/recreated.

AndroidAnnotations version:
4.2.0

Android compile SDK version:
25

Annotated code:

@IgnoreWhen(IgnoreWhen.State.VIEW_DESTROYED)

Expected generated code:

private volatile boolean viewDestroyed_ = true;

Actual generated code:

private volatile boolean viewDestroyed_;
