Add null check in animator

[f2069]

_isAnimatorSet has null check.

FishNet/Assets/FishNet/Runtime/Generated/Component/NetworkAnimator/NetworkAnimator.cs

Lines 376 to 381 in f8cdf25

	private bool _isAnimatorSet
	{
	get
	{
	bool failedChecks = (_animator == null || _animator.runtimeAnimatorController == null);
	return !failedChecks;

_canSynchronizeAnimator doesn't have null check.

FishNet/Assets/FishNet/Runtime/Generated/Component/NetworkAnimator/NetworkAnimator.cs

Lines 364 to 370 in f8cdf25

	private bool _canSynchronizeAnimator
	{
	get
	{
	bool enabled = (_animator.enabled || _synchronizeWhenDisabled);
	bool failedChecks = (!_isAnimatorSet || !enabled);
	return !failedChecks;

And periodically we have an error on server side.

MissingReferenceException: The object of type 'Animator' has been destroyed but you are still trying to access it.
Your script should either check if it is null or you should not destroy the object.

I modified it to be a little less redundant. _isAnimatorSet actually does a null check so if we put that first we can save the null check.

            get
            {
                if (!_isAnimatorSet)
                    return false;

                if (_animator.enabled || _synchronizeWhenDisabled)
                    return true;

                return false;
            }
