Fix issue with adding new elements in an array field.  The offset starts
at 0 and not at 1, however the code was adding elements at the nth+1
element.  Example:

      Existing:
         0: asdf
         1: hjkl

      Add element did this:
         0: asdf
         1: hjkl
         3: <new element>

      With this patch it should do this:
         0: asdf
         1: hjkl
         2: <new element>
