Fix refcounting on zend_empty_array in ext-uri

Fixes GH-19892

I just realize, there is a much simpler fix:

--- i/ext/uri/php_uri.c
+++ w/ext/uri/php_uri.c
@@ -308,7 +308,7 @@ static zend_result pass_errors_by_ref_and_free(zval *errors_zv, zval *errors)
                return SUCCESS;
        }
 
-       ZEND_TRY_ASSIGN_REF_ARR(errors_zv, Z_ARRVAL_P(errors));
+       ZEND_TRY_ASSIGN_REF_TMP(errors_zv, errors);
        if (EG(exception)) {
                return FAILURE;
        }

The assertion still makes sense to me, though.

Yeah that works too and seems like the best solution.
