JSON.ArrayLength is incorrect with empty string as value

[rwu2359]

If the array contains values which are an empty string i.e. "" the function will not return the correct number of items in the array
Suggest changing to

_values = JSONListKeys ( _array ; path )

This will return the correct number of full or empty slots in the array

Here's a test that demonstrates the error:
JSON.ArrayLength ( "[ 1, \"\", 3 ]" ; "" )
should give a result of 3, but instead gives 2.
The suggested fix by @rwu2359 would address this error.

I'm having trouble attaching files to the comment above, so I will try here:
I've attached a copy of the JSONAdditions.fmp12 file that give an example of the error, and a copy that includes the fix.
