Bumped .CFVERSION number to 3.27.1

Currently, classfilterdata() does not return a variable for
array_of_XXXs if given data structure's value do not comply completely
to given array_of_XXXs parameter.
On the other hand, classfilterdata() does return a variable when given
object_of_XXXs even if this variable does not completely comply to
object_of_XXXs.

This patch changes classfilterdata() to not return a variable as well
for object_of_XXXs in case given data structure's does not comply.
Also add an acceptance test for it.
This patch also fixes a compiler warning mayby-uninitialized of variable
remove in FnCallClassFilterData() in case parent is of type JSON object.
