Tweak isExplicitArrayConstructorInvocation function for correctness

Technically speaking, we should never be calling
`NameReferenceNode::getLastName` downstream of the `readNameReference`
method. It means while we're looping over each part of the name
reference, we're looking at the last part of the name each time.

This is a subtle correctness thing, there should be no behavior change.
