BUG: slicer.util.getFirstNodeByName: Should not return only visible nodes

This commits updates "getFirstNodeByName()" to leverage changes
integrated in r25160 (ENH: Update VTK to handle default values
for array parameters in python)

Now wrapping of methods with pointer parameter having a NULL default value
are supported, there is no need to hardcode the value of "byHideFromEditors"
to either [0] or [1].
