MDEV-19487: JSON_TYPE doesnt detect the type of String Values

Browse Source 
(returns NULL) and for Date/DateTime returns "INTEGER"

Analysis:
When the first character of json is scanned it is number. Based on that
integer is returned.
Fix:
Scan rest of the json before returning the final result to ensure json is
valid in the first place in order to have a valid type.
