        invalid.

7c7c0696e7 MDEV-11856 json_search doesn't search for values with double quotes 
character (").

        The my_wildcmp function doesn't expect the string parameter to
        have escapements, only the template. So the string
        should be unescaped if necessary.

e5377be211 MDEV-11562 Assertion `js->state == JST_VALUE' failed in check_contains(json_engine_t*, json_engine_t*). 
check_contains() fixed. When an item of an array is a complex
        structure, it can be half-read after the end of the recursive
        check_contains() call. So we just manually get to it's ending.
