MDEV-32007: JSON_VALUE and JSON_EXTRACT doesn't handle dash (-)

Browse Source 
as first character in key

Analysis:
While parsing the path, if '-' is encountered as a part of the key,
the state of the parser changes to error. Hence NULL is returned eventually.

Fix:
If '-' encountered as part of the key, change the state appropriately to
continue scanning the key.
