### Issue description

When creating a typed array from another base array, if the base array was gotten from get_tree().get_nodes_in_group(), you cannot create a typed array assigning a script different from null, otherwise the resulting array will be filled with nulls.

### WorkAround

Instead of using the output of get_tree().get_nodes_in_group() directly, the user can join it with an empty array
```gdscript
[]+get_tree().get_nodes_in_group()
```
and it will work as expected.
if (_p->array.size() == 0) {
		return -1;
	}
	Variant value = p_value;
	ERR_FAIL_COND_V(!_p->typed.validate(value, "rfind"), -1);
	if (p_from < 0) {
		
		p_from = _p->array.size() + p_from;
	}
	if (p_from < 0 || p_from >= _p->array.size()) {
		
		p_from = _p->array.size() - 1;
	}
	for (int i = p_from; i >= 0; i--) {
		if (StringLikeVariantComparator::compare(_p->array[i], value)) {
			return i;
		}
	}
	return -1;
}
int Array::count(const Variant &p_value) const {
