Fix #412

Testing main again (VM with nil osProfile, Windows or Linux):

_../go/bin/aztfexport query --continue --non-interactive --recursive 'type =~ "microsoft.c
ompute/virtualmachines" and name =~ "XXXXXX"'

A single static variable reference is required: only attribute access and
indexing with constant keys. No calculations, function calls, template
expressions, etc are allowed here.

Running fine with VMs with no nil osProfile (Linux or Windows).

@JavierCCC What is the result when you run aztft -api <resource id> on that problematic resource? (you can install aztft by go install github.com/magodo/aztft@main).

BTW, do you know how can I create a legacy VM that have a OS disk attached, so that I can reproduce this locally?

I've figured out the cause, will commit the fixes soon.

@JavierCCC It should work now, please take another try! Thank you!
