fix: values matcher doesn't work if values is array with keys

[tienvx]

• On consumer: example values will be array with keys:

     'values' => Array (
-        0 => 'a'
-        1 => 'bb'
-        2 => 'ccc'
+        'a' => 'a'
+        'b' => 'bb'
+        'c' => 'ccc'
     )

• On provider: got this error on verification:
