Fix a null pointer crash in cJSON_ReplaceItemViaPointer (#726)

If the parent passed in cJSON_ReplaceItemViaPointer has not a child, which means parent->child is null, a null pointer dereference crash will be happened inside cJSON_ReplaceItemViaPointer.

This commit adds the NULL check of `parent->child` beforehand to inform user such incorrect usage.
