Fix null reference exception when awaiting null.

Browse Source 
DynamicImageProvider:CreateImageAsync was not marked as async. When returning null the await BaseDynamicImageProvider:FetchToFileInternal would throw a null reference exception. An alternative solution would be to wrap the null return in Task.FromResult.

Object reference not set to an instance of an object.
