Fix: Consider index passed, even if the current domain is present

[kounelisagis]

This PR fixes an issue originating from #2156, which resulted in the current domain being used whenever it was present. This caused problems when indexing with an explicit idx while a current domain was present, leading to idx and nonempty domain not being used.

I would like to see a user-level repro script demonstrating the problem at the UX level, but, I suppose your unit-test case suffices for me to be able to reconstruct one.

I would also like to see some provenance of how/where this error was reported. Maybe just a Shortcut hyperlink in the Description section.

A user-level repro script is available on the Shortcut mentioned.

Thanks @kounelisagis !

When is this line false?

[kounelisagis]

This is true when no explicit index is requested (i.e., A[:]) and the array has a non-empty current domain. In all other cases, this is false.
