MDEV-32287: JSON_EXTRACT not returning multiple values for same path

Browse Source 
Analysis:
When scanning json and getting the exact path at each step, if a path
is reached, we end up adding the item in the result and immediately get the
next item which results in current path changing.
Fix:
Instead of immediately returning the item, count the occurences of the path
in argument and append in the result as needed.
