Fix the tests in TestInitDataTypes

Description

Fixes the tests in the TestInitDataTypes class

@gigiblender completed my pending work towards the support of Factory Methods for the Panama Collections.

This PR allows developers to use factory methods from the TornadoNativeArray types that can be combined into Tornado Task-Graphs

FloatArray array = new FloatArray(1024 * 1024);
TaskGraph taskGraph = new TaskGraph("graph") //
    .transferToDevice(DataTransferMode.FIRST_EXECUTION, array) //
    .task("init", FloatArray::initialize, array, 2.0f) //
    .transferToHost(DataTransferMode.EVERY_EXECUTION, array);

ImmutableTaskGraph immutableTaskGraph = taskGraph.snapshot();
TornadoExecutionPlan executionPlan = new TornadoExecutionPlan(immutableTaskGraph);
executionPlan.execute();
