Here the issue is different.
when running engine-setup the WGT iso is injected while the iso domain is
not yet active.
At engine setup done, you'll have the engine, the inactive iso domain and
the iso within it but only if you create the iso domain with engine-setup.

If you run engine-setup, create your own iso domain, and then on upgrade
you run again engine-setup, WGT is not uploaded there.

So the existing WGT upload mechanism already is limited to only those
installations born with iso domain creation on the same host.

Since we have iso-uploader and we'll have in 4.1 the ISO uploaded from web
ui, I really think this mechanism can be dropped since it covers only what
it seems to be a corner case.
